I can speak for the Lefty Grove cards from the set. The images on his 1982 and 1983 Big League cards were NOT used on any vintage baseball cards, but were used on a few of his cards produced in the last 30 years or so. I know, though, that the images on Lefty's cards were made from real pictures taken by a notable baseball photographer (someone like Conlon or Burke...).
I hope this helps...
