The first fragrance exclusively for gay men?

It’s funny what weird and wonderful things you come across while Googling fragrance ads in the name of research. I mean, just look at this 1978 ad for Reo – touted as the world’s first cologne exclusively for gay men.  To say I was shocked would be an understatement. After all,  it proves that someone got there nearly 20 years before Thierry Mugler did with A*Men. Wonder what it smelt like?
