1981 Fleer has a minor flaw that had escaped me for the past 32 years… Take a look at the baseball in the lower left:
The “stitching” is wrong. Both the top and bottom stitching run in the same direction, while on a real baseball the stitching goes in opposite directions.
Well, OK, it appears as if it’s going in opposite directions when viewed from that angle; in reality it’s going in one direction – around the ball and then back again.
For what it’s worth, Topps got it right in 1975…
…and in 1979.
