Without filling up this with links, you might look at just the one at:
https://en.wikipedia.org/wiki/Picture_disc
     The Wiki article has links to books, collectors group, et al.
     There are or were a few among the ARSC membership who collected 
these; but that could have been years ago in 1965 when I initiated the 
meetings which led to ARSC incorporation and founding in 1966. I was 
active as officer from start through 1972 (my wife died in 1970, and 
while a bit active on committees, I finally left for a while in 82 and 
again in 2006. I'm back now because I was asked to join a panel on ARSC 
history at the 50th Anniversary in Bloomington...there were only four of 
us there from those early days.
     I don't know if the membership directory has a way to search for 
keywords or not; if so, searching for picture records would bring up a 
few members for contacting.
     Also not everyone in ARSC is on the ARSCLIB list, maybe not even 
ARSCLIST, so may not have seen your post.
