You be reading the title of this post and be thinking who is Milt Thompson and why would someone who is not related to him spend $8 for his baseball card. Thompson was drafted in the 1979 second round by the Braves and go on to play in the Majors from 1984-1996. He was more of a pitch hitter/fourth outfielder type of player, but during the late 80s and early 90s he was somewhat of a regular for the Phillies and Cardinals. He played for the Cardinals from 1989-1992 on some very bad teams, thus the increase in playing time.
Just like every other player during that time period, Thompson had plenty of cards being overproduced by the 5 major companies. Leaf entered into the mix in 1990 with a brand that was somewhat of a premium.
