Always keeping an eye out for the unusual, I noticed this original Congress 606 (Hochman's US6) with Dundreary type 1 Joker and Purple geometric backs. Obviously it has to be an 1880's version, but those are listed in Hochman's Encyclopedia Of American Playing Cards as having "geometric red, blue or black" backs. Obviously this IS original, but where how did Gene Hochman & Tom both miss the fact that there are at least a few Purple backed decks? Must be a rare(r) version, not to even be mentioned as existing in Hochman's? We'll see, Tom - what do you think about this one? Just not as well-known perhaps, or is it truly an unusual find? Words of wisdom, sir? This deck is in fabulous shape, since the 606 brand was the best made of the original brands. I take such crappy pix myself - I used those from the listing on eBay instead. The joker is actually not as dark as it appears in the photo, it is clean and crisp and all cards are in excellent condition for an open deck likely some 130+ years old.
