The 1967 Topps Player Pin-Up inserts found in certain 1967 packs found its way into Canada for 1968, and were offered on even rougher, cheaper pulp paper than that used by Topps.  They also suffer from fold lines and as a result, intact surviving examples are tough to find and often end up with technical grades that can seem a  bit harsh. This Clemente exhibits typical centering and toning for the O-Pee-Chee issue and a slight separation at the bottom of the vertical fold. Tough to find these.
