When is a comic not a comic?

When it is a Gang by Richard Prince

This looks like a Abstract Comic to me

There isn't many images of his 'gangs' on the net but what I saw struck me as being comics under another name. Or at least being able to be interpreted as comics, abstract or otherwise. I can see why they are not comics, he is interested in different ideas, they are collections or gangs of similar images. Still I find them really interesting in terms of my own abstract comics exploration.

So what do people think? Are they Comics? Does anyone know more about him? Is there any other 'fine arts' artists who don't know they are making abstract comics?

Thanks Dick Whyte for showing me Richard Prince.
