1975 Topps #622 Fred Lynn ROOKIE (Red Sox)

O-Pee-Chee (OPC) based in Ontario Canada, is mostly thought of as the Canadian version of Topps but it actually pre-dates Topps by many years.

In 1933, OPC issued their first sports card set, the V304 Hockey cards and is currently in the tens of thousands. Their first baseball set was issued in 1937. It was similar to the 1934 Goudeys and Batter-Ups and the top player was Joe Dimaggio.

O-Pee-Chee created baseball card sets similar to TOpps from 1965 into the 1990's. At first OPC sets were much smaller than Topps and included just the first few series. Fronts & backs were nearly identical but with a small "Printed in Canada" on the back and the card stock was slightly different.

Baseball being much less popular in Canada, OPC print runs of their early years were between 1% and 10% of Topps making them exceedingly scarce !!!

Starting in 1970, Canadian legislation demanded all items produced in Canada carry both French & English so OPC baseball cards became bilingual with both languages included.
Other OPC differences include:
1971, OPC even changed the back design to a much more interesting back and also offered 14 different card photos not in the Topps set.
1972 OPC included a card of Gil Hodges mentioning his death that was not a part of the Topps set.
1974 OPC did not include any "Washington Nationals" variations.
1977 the card format remained like Topps but almost 1/3 of the OPC set had different poses/images than Topps.
In late 1970's, OPC card fronts appeared similar to Topps but sometimes included traded information saying "Now with XXXX". They were able to do this as the OPC cards were printed much later into the season.
