Designed by Herb Hancock of Ontario, Canada. Published by Stancraft Products of St. Paul Minn., under the brand name Hoyle. The Split Deck Playing Cards box includes two split decks, one with red backs and one with blue backs, and a rule book explaining how to adapt several games for use with the split decks: Bridge, Cribbage, Rummy, Hearts, Poker. When holding a hand of several of these cards, they can be fanned out to show the white halves, or rotated and fanned out to show the yellow halves instead. These will be two very different hands.
