This is fascinating! Would it be possible to add some explanations for some of the gay ads? I feel a little clueless but I don't really understand why some of those are targeting the gay community.

Thanks! Maybe I'll add some detail. Some of them are in the eye of the beholder, and maybe I take a little liberty :) It's not that they are targeting the gay community directly, but they may have subtle homoerotic wink and a nod... They definitely are not overt and would have gone over the heads of most people at the time.
