Henry Rinn Jr. loved roaming Baltimore streets in the late 1800s. With his penchant for photography and unusual perspective, Rinn left a legacy of 250 collectible vintage postcards and much, much more. His first series of black-and-white picture postcards started in 1898.
What postcards are bestsellers today? The people most likely to have the pulse of the hobby are dealers who offer thousands of cards to the public every year.
