1971 O-Pee-Chee/OPC Baseball Cards![]() ![]() ![]() OPC did make several changes to their 1971 set including a complete redesign of the card backs. OPC also changed over 20 cards including the first "Traded" cards and added more EXPOS cards to the set including #202 and #289. 1971 OPC's short prints are legendary, at only 5% of Topps' production, making this set very rare even in Canada. Some say 1971 OPC short print high numbers are even scarcer than the very, very scarce 1952 Topps highs where most ended up being dumped deep into the Atlantic ocean.

The first baseball trading cards date back to 1869. For many years, baseball cards were packaged in packs of tobacco as a way to increase sales the same way that today prizes are packaged in boxes of cereal. In the 1920's and 1930's, candy and gum companies started packaging baseball cards in their products as well.
Baseball card production was virtually halted in the early 1940's due to paper shortages created by World War II. The "Modern Era" of baseball cards began in 1948 when Bowman Gum Inc. offered one card and one piece of gum in a pack for a penny.
The first important football set was the Mayo set featuring college players in 1984. Other than the 1935 National Chicle set no other key football set was issued until 1948 when noth Bowman and Leaf produced sets.
