Super cool baseball card-related item. This is a check that was made out to Negro Leaguer Leon Day for $10 from 1993. Day has endorsed the check on the reverse. But the coolest part is the memo line which reads "2 BB Card". Check is from Puerto Rican collector, Alberto Baco. What cards did he purchase? Day has two Puerto Rican baseball cards: 1949-50 Toleteros and 1951-52 Denia.
