You expect to find a gaggle of great players on Topps league leader cards and this 1968 O-Pee-Chee NL RBI Leaders delivers the goods with three Hall-of-Famers front and center. Their fourth effort under their license from Topps saw 196 cards issued in Canada and this is a high grade example for both the set and country of issue. There's strong corners and edges, with no evident chipping front or back and some terrific centering. There's also a classic O-Pee-Chee ragged cut apparent above the long side.  You can just sense that Cepeda, Clemente and Aaron are plotting to do some damage to NL pitchers.
