You are welcome, but no "expertise" for this and I am not saying anything about authenticity - I am literally just reading the names off the cards. Terry Moore, Margaret Leighton, Jeff Stone...these are, roughly speaking, 1950's folks.
No Problem. Sorry if I sounded snippy - not having a good day. Listening to the "I don't have a budget can you do my work for me?" song yet again - not in this field but another area of research I am involved in. It is...not a catchy tune.
I am sure others will recognize the rest of the names you posted.
