never seen it and just a shot-in-the-dark on my part - with no manufacturer shown in your posted image, it looks like some sort of game or perhaps a quiz card(?)...

maybe (?) the blank white area is to fill in a the last name of a pitcher nicknamed "The Barber" - SAL MAGLIE - by plucking letters shown in the names listed below, as the letters M-A-G-L-I-E could be found???

while I could be completely full of sh!t *wouldn't be the first time* or totally overthinking this, that's MY (VERY!) wild-ass guess.

edited to add: could be a Laughlin / Fleer issue, as the cartoon graphics are very similar.
