Someone long ago, a very dedicated Virginia "Summit" cigarette smoker I'd guess!, must have collected hundreds of these free giveaway domino cards (one per each tin of Summits) in order to form this complete double six deck. Not too surprising then that I have not found another set of these, which I'd guess date to the 1920s or 30s, anywhere!
The graphics of the faces I think are just terrific, with red borders, tiny images of the cards repeated in the corners, and the spots very dark green with black outlines and red dots in the centers. Except for the colors, they're quite similar to a couple of decks of Charles Goodall & Son, London decks I've had, who may have been the producer of these as well. The backs feature red on white text courtesy of the International Tobacco Co., London, including instructions for the number of cards and certificates required to cash in for a "fine wood and bone set...free for all advertising matter"!
In truly excellent condition. No box as there would not have been one. 2 3/8" x 1 3/8" ea.
