I believe that picture is contained as one the pictures of the MCS in this paperback book that I bought at Barnes and Noble for my personal collection, since I worked at the MCS in the 70s.

It is in a storage rental since I moved, so I don't have access to the book right now, but if you go to a BN, and look for that book, it might have the name of the owner of the picture listed in the credits section.
