This standard-size set of cards was produced in an effort to establish a Canadian baseball card market much as Topps' affiliate O-Pee-Chee had done. The Donruss Company in conjunction with its new parent Leaf Company issued this set to the Canadian market. The set was later released in the United States through hobby dealer channels. The cards were issued in wax packs. A piece of a large Lou Gehrig puzzle was inserted in each pack. Aside from card number differences the cards are essentially the same as the Donruss U.S. regular issue of the cards of the same players; however the backs are in both French and English. Two cards, Dick Perez artwork of Tim Raines (252) and Dave Stieb (251), are called Canadian Greats (CG) and are not contained in the Donruss U.S. set. As in most Canadian sets, the players featured are heavily biased towards Canadian teams and those American teams closest to the Canadian border. Diamond Kings (numbers 1-26 denoted DK) and Rated Rookies (number 27 denoted RR) are included just as in the American set. Those players selected for and included as Diamond Kings do not have a regular card in the set. The player cards are numbered on the back. The checklist cards (listed at the end of the list below) are numbered one, two and three (but are not given a traditional card number); the Diamond Kings checklist card is unnumbered; and the Lou Gehrig puzzle card is mistakenly numbered 635. Key cards in this set include Roger Clemens and Dwight Gooden in their Rookie Card year.
