Which were the Gayest disco album covers of all time?

The first one that came to mind was Slide...Easy In from 1977.

Then the Italian disco record by Macho...I'm a Man, from 1978.

They then followed it up with another Roll in 1980.

Another Italian release was the sublime Easy Going with the classic Baby, I Love You.  This 1978 gem features Claudio Simonetti who went on to become one of the most important names in italo disco and club D.J. Paolo Micioni who also had quite a list of accomplishments after this early endeavor.

This back cover is quite camp but that would have to be featured in a whole other post in the future at some point Disco Camp album covers.

The Ritchie Family's Bad Reputation from 1979.  What were they thinking?

Prince's 1980 release Dirty Mind before he had really broken big on the pop charts.  Prince is a jehovah witness and has never come out as gay or bi-sexual, no comment.

Then we have the 1984 Hi NRG twelve inch by The 501's We are Invincible.

I'm going to give The Rolling Stones Sticky Fingers l.p. from 1971 an honorable mention because it's not disco.  

I consider this one of the best album covers of all time.
