Andy Warhol: 'Ave A Banana!

From the exhibition, Andy Warhol At Privatus.
Featuring some explicit Polaroids, at some London swank gallery. 
"Viewing by appointment only".
Smell 'er!
You can see a nice selection for free on that there weblink above.

PS I once met a young homosexual gentleman who, whilst innocently walking the streets of London in the late-80s, had Mr Warhol come up to him and ask if he could take his picture.
"Oh, yes," he gushed excitedly, "please do..."
Andy then took a photo of his shoes.
True story.
