I have always believed that inspiration can't really be explained since usually it's a feeling evoked by an idea. But here are some more images that are floating around my head.
Katharine Hepburn photographed by Richard Avedon.
Clyde Barrow.

Serge Gainsbourg and Jane Birkin. Not sure of the photographer. Seemed fitting to follow clyde barrow since Gainsbourg turned his and Bonnie Parkers story into a jaunty tune in Bonnie and Clyde.

I always have been fascinated by mythical sea creatures. I think this image captures pretty well why.
