Speaking of bad airbrush jobs, there's the Charlie Sands/Angels picture in the Batters Pack. Not only did they put on the wrong hat (Sands was a Pirate 1971 and Spring Training 1972, when the Angels wore the "slipped halo" hats with the lowercase "a"), but the "a" on those hats was nowhere near as big as Topps created it in that pic.
This picture of Sands, used for his 1975 Topps card, is (to my knowledge) un-retouched. At least the "A" here looks normal.
