1962 Post Cereal Canadian #71 Gene Woodling. Rev neg Canadian version is on left, compared to the American version on the right.
1979 Hostess #105A Bob Bailor. Pic is on right and has a corrected version in the Hostess set. The same correct version of the pic is used for the 1978 Topps card of Bailor, pictured on the left.
1980 Pepsi Cola All-Stars Prototype #9 Ron Guidry (UER). You will never find this card because it is impossibly rare.
1992 Pepsi Canada #5A Tom Glavine. Reverse is on the left. Glavine is a lefty in real life and you can just make out the backwards E on the back of his jersey.
1994 Kraft Superstars #17 Barry Bonds. Since the logos are airbrushed out in the pic, the way you can tell is that Bonds is pictured as a righty when he is actually a lefty in reality.
1998 Kenner Starting Lineup #4 Kevin Brown (UER, unlisted)
1968 Champion Corn Flakes #8A13 Don Maynard (UER, unlisted)
1969 Glendale Stamps #111 Mel Farr (UER, unlisted)
1969 Glendale Stamps #175 Bob Griese (UER, unlisted)
The are also reverse negatives of the 1948 Winner Candy #48 Roberto Clemente and the 1976 Hostess unissued proof of the #63 Ron Cey card. Both are listed in price guides but I have not yet found scans of either one.
The next post be on pre-war baseball cards....
