Let's go and give former longtime pitcher Don McMahon a "Then and Now" card as part of the 1972 set, his final appearance as a player in a Topps set:
By the time he retired after the 1974 season, McMahon put together a wonderful 18-year career that had him appear in 874 games, all but two out of the bullpen, with 152 saves and a nice 2.96 earned run average over 1310.2 innings.
Playing for seven organizations between 1957 and 1974 he was a valuable arm off the bench, posting ten seasons of sub-3.00 ERA, with five of them coming in under 2.00, and in 1957 with the Milwaukee Braves and in 1968 with the Detroit Tigers, he was a World Champion for good measure.
To be honest, McMahon should have had a card in both the 1973 and 1974 Topps sets. I already created on for the 1973 omission, but look for my 1974 and possibly 1975 "Career Capper" in the near future!
