There were 10 Indianapolis players in the group, clearly dating to 1934 - incl. manager Red Killifer. -
They certainly appear to me to be identical to the Gold Medal Foods cards I have researched in Old Cardboard (articles in issues 6 and 7)
They were with a GMF World Series complete set - the seller says he got them from an estate sale near Indy, so I have to presume they have been in family hands since 1934.
