1971 was the first year the Topps and O-Pee-Chee sets had the same number of cards, although the extant examples from the Canadian side are about 20 times tougher than their US counterparts. Such is the case with this sweet looking PSA 6 of the 1971 World Champion Pirates. Some edge wear - so common with this set -is present but doesn't detract. The photo is vivid and pops against the black borders on what is a tougher semi-high from the set.
