That is a showing I’d attend.
Many years ago, when I was living in the French Quarter, a local men’s bar had a similar photo album. It was called the “Dick-ionary”. A collection of men that frequented the bar. I thought it great to see how my i could recognize. Most of us played volleyball, tennis, etc. so had seen each other in the locker room often, or in the dark rooms at various clubs (including Club New Orleans).
I think men should be more comfortable with being seen by other men. Just consider the options. Grouped by various sports, leather clubs, or even neighborhoods in the city.
