1945 Mexican League card of Cuban Juan Montero. Also includes his biography booklet. See lot #16 for another example from this set that includes the booklet. The cards and booklets each measure about 1 7/8" by 2 3/4". That's for the booklets when folded. This is a great set of color cards that rarely surface. And this auction is the first time I'm aware of that an individual player booklet has ever been offered for sale, either public or private.
