Exhibit 4 on 1 Stock Variations
 

I've had this card for decades:

It is printed on two-sided finished stock. I do know that ESCO made some cards in similar stocks in NS and boxing, but I haven't seen baseball other than this one. However, if this one exists there must be a sheet (32) of them.

Anyone else have one of these?
