1963 Beisbolistas card #8 of Baltimore Orioles fan favorite, Miguel "Mike" Cuellar. Pictured here with Monterrey of the Mexican League. This is part a previously unknown issue from Mexico. The
set contains 157 cards, or at least there are 157 numbered spots in the
album. Many of the cards have never been seen, including ones of
Roberto Clemente and Frank Robinson. Most of the cards are players in
the Mexican League, but there are also a small handful of Major Leaguers
as well. Each card is the only known example. Cards measure 1 7/8" by
2". The backs are blank.
