Collectors Chase Cast Iron Advertising Pups

The Griswold Manufacturing Company along with many other businesses used advertising Pups as promotional giveaways in the early to mid-1900s.

Did you know that some of these 1-5/8” tall cast iron advertising Pups can bring a price close to $1,000?

I didn’t think so.

Joe Zawadowski of Durham, North Carolina, collects vintage cast iron advertising Pups. The Griswold Manufacturing Company along with many other businesses used the Pups as promotional giveaways in the early to mid-1900s.

Joe Zawadowski’s Collection of Advertising Pups

Joe’s interest in cast iron advertising Pups began about five years ago when his wife Nancy was given “Big Red,” a red advertising Pup made for Mathews Steel Company. Nancy’s grandfathers had both worked for Mathews Steel. Big Red lived on Nancy’s mother’s bedroom bureau when Nancy was growing up.

Papa Pup “Big Red,” the centerpiece of the cast iron Pup collection of Joe Zawadowski. Flanking Big Red are two unmarked Pups hand-painted by Joe. The second row shows some of Joe’s “Angry Dogs.” The angry dogs – also called bridge pencil guard dogs – have a round hole through their jowls designed to hold a pencil or pen. Some angry dogs were made with no tag; they were sold as paperweights or bridge pencil holders. Joe’s Angry Dogs in this photo have tags around their necks which are from the 1933-34 Century of Progress exhibition in Chicago. One has a tag simply reading “Chicago Souvenir.”

Big Red piqued Joe’s interest. Big Red is the size of what some call “papa” Pups – Big Red is all of 2” tall.

Joe began looking for and acquiring the “typically-sized” 1-5/8” tall Pups here and there on his travels. He now has 218 cast iron Pups. He considers Big Red to be their “founding father.”

Joe’s collection (some collectors call their Pups a “kennel of Pups” or “litter of Pups”) continues to grow, but it is by no means the most extensive collection of Pups. I know of one collector who at one time had over 700 cast iron advertising Pups, and there are probably others with equally large collections.

The little Pups were not used only to promote businesses, though that was most common. Technical students made the Pups to learn the craft of casting iron. Churches and schools awarded the Pups for good attendance.

Pups were marked in different ways. Business names were inscribed on the Pups, painted on the Pups, or cast onto the Pups. Many Pups were not marked at all.

Griswold advertising Pups

The Griswold Manufacturing Company of Erie, Pennsylvania had two production runs of advertising Pups: the first in 1937 and the second in 1951. The 1937 Pups are harder to find and correspondingly command a higher price.

Three thousand Pups were reportedly produced in the 1951 production run. Griswold employees handed out 2,000 Pups during Erie’s August 11, 1951 centennial parade. The rest were given to employees and loyal customers.

Identifying authentic Griswold Pups

Griswold Pups are sought after by collectors, and reproductions abound. As I was writing this article, I did a quick search on eBay for “Griswold Pup.”

Of the eight Pups listed, six were reproductions.

Authentic Griswold Pups were made in both cast iron and aluminum. Joe taught me how to distinguish a genuine from a reproduction Griswold Pup.

Reproduction Griswold Pup. Note the defined toes, lack of defined collar, different nose and eye shape, poor, rough casting. Authentic Griswold Pups have fine casting; not the rough texture you see here. Authentic Griswold Pups do not have raised lettering. Also note the flatness of the head.

Real or repro?

  • An authentic Griswold Pup will always have the words GRISWOLD and PUP incised on its back in clear lettering. If the lettering is sloppy, it’s not Griswold.
  • An authentic Griswold Pup has the words incised on its back. It does not have raised lettering.
  • Almost all Griswold Pups have a ghost mark “HINES” on the rump. Fakes do not.
  • Griswold Pups do not have defined toes on the paws.
  • The head of an authentic Griswold Pup is more rounded than that of a fake.
  • An authentic Griswold Pup will have hollows representing pupils in the eyes.
  • The spacing of “GRISWOLD” and “PUP” on the rump is further apart on an authentic Griswold than on a fake.
  • The tail on an authentic Griswold is “smoothed” on the underside to render the appearance of a slightly upturned tail.
  • Authentic Griswold Pups come in black iron, grey-green finish (called the “grey ghost”), black japanned iron, and aluminum.

"Griswold" silver and gold-plated Pups

There is yet another Griswold-marked Pup that was not made by Griswold. These are known in the cast iron collecting world as the infamous “silver” Pups.

A man in Oregon made a “Griswold fantasy piece” circa the early 1990s. He cast Pups with the Griswold markings and offered them for sale.

The man made it clear that Griswold did not produce the Pups. The Pups were cast in solid silver. He sold them in silver as well as with 24-karat gold plate over the silver.

The problem with fantasy pieces such as this, of course, is that when the piece passes through hands, it may be thought to be (or represented as) an authentic Griswold-made item.

That was the case with two of these silver Pups. A person represented them to be authentic Griswold-made pieces and consigned two of the Pups to an auction in 1994. Each Pup sold for $1,175. It was soon learned that the Pups were not Griswold-made; the auction house refunded the money.

Pricing of Pups

The value of cast iron advertising Pups depends largely upon the condition and the business for which they were cast. The most common found Pups are unmarked. Of the marked pieces, those that carry the name “HINES” and “BUCKI CARBONS” are easier to find than others. Because the Pups are more common, the price they bring is less than those of harder-to-find Pups.

eBay Pup sales

Joe has kept a log of eBay authentic Pup sales since 2013. The highest price he saw a Pup bring was one marked “HERCULES.” It sold for $904.74. Two other HERCULES Pups were sold since 2013; one for over $500 and the other for $260.85. No wonder, then, that Joe was delighted when he found his own HERCULES Pup.

After HERCULES, the next-highest priced Pup sold carried the name “McPup.” It sold for $852.14. Third-highest was a Pup marked ANDERSON INSURANCE COMPANY that sold for $300.26.

Other Pups that are highly sought-after and command a high price include ones marked “Kaiser-Frazer” and “Oval Tube.” Those Pups sell for hundreds of dollars in good condition.

Griswold Pup pricing

Authentic Griswold Pups can also bring a substantial price. Joe has kept track of the prices paid on eBay since 2013 for genuine Griswold Pups.

Black iron Pup and black japanned Pup without the number 30 on the back of the head (first production – 1937)

None sold. These are reputed to be the hardest Griswold Pup to find. Presumably, one in excellent condition would bring a higher price than the others given its scarcity.

Joe’s advice for new Pup collectors

I asked Joe what advice he had for the new Pup collector. Here is Joe’s advice, straight from Joe himself.

Pups turn up in unexpected places. Search everywhere: the internet, antique shops, auctions, estate sales, etc. Most of [Joe’s] Pups have come from eBay, but some of the rarest were personal finds in other venues. The more places one searches, the better the odds of finding Pups. Keep a sharp eye when personally searching. Pups are quickly passed over if one does not have a good eye for spotting them.

Don’t be afraid of fakes. The Griswold Pup is the only faked or copied Pup. Learn how to spot the real ones, and you will be fine. Once in a while, one comes across a ‘backyard caster’ attempt using a Bucki Carbons Ribbons or other common Pup as a pattern. These home projects are generally obvious and inexpensive. I consider them collectible for what they are.

If you can afford it, buy it when you find it. In more than five years of collecting, there have been many Pups for which I have only seen one example. I’m happy now I was able to add them to my collection, even though I felt I paid an awful lot at the time.

Get involved with other collectors. They will help you find the Pups you are searching for and might even part with some of their duplicates. Both the Griswold and Cast Iron Cookware Association and the Wagner and Griswold Society have knowledgeable Pup collectors in their membership. Both organizations also have valuable information about Pups on their websites that are only available to members.

Be patient and persistent, and you will eventually find the advertising Pups you seek.

3. A Griswold “fantasy piece” is a product that may look like a Griswold product but is not, and is not offered as so. A “Griswold reproduction piece,” on the other hand, is a product that looks like it may be Griswold but it is not; and is offered as an authentic Griswold-made piece.

4. The maker sold the silver Pups for $250. The gold-plated Pups were offered at $295. 

5. I paid $275 to a collector for my beautiful black iron Griswold Pup with the 30 on its head in 2014. By today’s market, it appears I overpaid.
