Here is a pretty early version of a very commonly reproduced deck. This one has a piece of the tax stamp , along with the obvious copyright date on the "LWB" has helped with the dating.
How cool! I just bought an old deck of these, too, but they aren't as old as yours - I was actually thinking of asking on here if anyone knew how to figure out the publication year. They're in a little box with a nicely worn brown velveteen cover, stamped "The U.S. Playing Card Co., Cincinnati, OH". The backs are the newer purple version with the witch by the campfire. Any ideas?
I love these cards, they smell like an old bookstore! They're in great shape, too, though I think they were used a lot.
