I've never seen a checklist, but I think it's a unique issue. Here's everything I know about it:

It's by F. R. Woods, a memorabilia dealer who is "just a few doors down the street from the Hall of Fame, and is still in business today - selling unique baseball items from the past." They used to advertise in Baseball Digest when I was a kid (1960s).

The photos came in a set called "All-Star Picture Photo Pak set of 12 photos". One complete set offered at auction identified it as from 1969; individual photos offered on eBay over the years have identified the photos as from 1970 and/or 1971.

The photos are on delicate, textured linen-type stock, with blank backs.

I've verified 11 different photos so far: Banks, Bench, Killebrew, Mays, McCovey, Murcer, Powell, Robinson (Brooks), Seaver, Staub, Yaz.

Perhaps the checklist includes only 12 players, and the same photos were sent out every year for 3 years with the date changed only on the packaging? I'd be surprised, however, if an issue from either 1969 or 1970 would include Murcer as an All-Star, unless they just wanted a current NY player in the set, and he was the best available.

Since F. R. Woods appears to still be in business, maybe I'll call and see if anyone there recalls anything about this one.
