Looks like a bunch of these (see above link) sold recently on ebay including the one Larry referenced. I have a couple of copies of that Horne's booster club team composite. I don't believe that indicates it in any way is a "checklist" of appearances.
Cross referencing the ad from the post gazette September 15th 1960 (That newspaper archive is INCREDIBLE!) indicating that Clemente, Stuart, Burgess and Maz were appearing that day with the Stuart and Burgess photos that sold on ebay and have Sept 15 dating on them would seem to be strong evidence that a Maz and Clemente exist as well!
Other dates from the other players that sold include:
Groat - May 26, 1960 (no papers available from archive for that date)
Skinner May26, 1960
Groat April 17, 1961 See ad from newspaper archive:

Cool - It's been a LONG time since I've been able to add something to my want list.
