Did Diane von Furstenberg have her portrait painted by Andy Warhol and did she put the picture on a T-shirt?
They were friends. He snapped a polaroid of her and then decided
to paint her; this was in the 70s In the 90s, they put the print on
a t-shirt b/c (a) that is in the spirit of Andy and (b) people love
and want that portraint -- what better way to bring it to the
masses than on a t-shirt! I'm sure there is a more thorough and
complete answer, but we'd need to ask Diane herself!
