Anyone have info on early 70's Stadium Arena Cards 11x14
 

Hi Gang:

Does anyone have info/checklist for the early 70's 11x14 Stadium Arena Cards?

A friend has a group of mostly baseball including Bench, Clemente, Carlton, Seaver, B. Robinson (different poses) as well as non baseball like Namath, Bobby Clarke, Hull etc.

Many are unopened in original cello

Any help appreciated

Sorry photos are not upright.
