Gay San Antonio, 1957

I spotted these photos on eBay a while back; they were each in individual ads.
And while the dealer offered no background information, I realized this was a
group of friends, to me very likely gay. The processing marks indicate they
were done in 1957 in San Antonio. They were scattered over 36 ads, and
I did not buy any of them, but I carefully did screen grabs of them all.
