1953 - 55 Howard Photo
 

I do not know all that much on this set, so I figured I'd ask.

From PSA .... "The rarity of this issue is cause for the little information known about it. Seemingly distributed over the course of several years, these 3-1/2”x5-5/8” cards have a glossy black and white front photo and a simple postcard back. A rubber stamp on the reverse connects the card to “Howard Photo Service, N.Y.C.” There are currently seven known cards in the set checklist, including two poses for Bob Turley and Willie Mays with two differing back types. It is possible that the checklist is incomplete."

I remember reading somewhere that these were designed for 7up customers as well as the cards never getting distributed. Not sure where I read that so any insight would be appreciated.

Thanks in advance!
