30-Day Baseball Card Challenge: Day 22

"A card of a common player that always seemed to elude you." The first set I ever collected was 1987 Topps; both 1987 and 1988 Topps were the cards I had by far the most of when I was a kid. Later as an adult they were the first two sets I completed, in 2007. Gary Gaetti was one of the last cards I need for both sets. I was probably 775 cards into both of them before I got Gaetti for either one.
