WTF is this card?
 

Blank backed, real photo, definitely prewar based on silvering. My guess is UK given the fighter and the city listed. It is larger than most tobacco inserts of the day.

It sort of looks like an Ogdens, but there isn't much that's really "right" about it to be one of those.

My guess is that is is a cut-out from a handbill or program.

Same photo (dated 1930) as found here:

Hmmm. I've had that piece before. I've got it listed as a promotional ad card in my files. Wish I could remember the dimensions, but I think it was a little bigger then a postcard.

Adam's piece might be a promo from that fight, or perhaps a managerial giveaway.

Mine is smaller than a baseball card. My guess was a fighter issued promo card of some type.
