Here's an interesting card I picked up - 1957 Topps Duane Putnam - but not so fast. Check out the back. This must have been cut from a 3-card advertisement strip. I've seen ad strips for other Topps years/sets, but not 1957. Has anyone seen one from this year uncut? I'm just wondering if the strip was vertical or horizontal. Looks like it was the top card on a vertical strip to me.
