I typically don't scan the backs of cards too often but in the case of 60s and early 70s OPC cards, the fronts are identical to the Topps issues and most of the Topps versions of these cards have been previously featured in the blog if you really want to check them out.
Chris, thanks for the trade and the big infusion of Canadian Cardboard! I really appreciate the trade and hope that you enjoyed the Blue Jays I sent your way. Thanks!!!
