The Clown with Red Hair

Barry Leighton jones is a fine artist with illustration and cartooning influences (It seems to me) from England. During the 1970's he did a series of clown based paintings that were very popular. If anyone has any information about him, beyond what's available on his website, I'd love to know.

From his website:
The 'Clown With Red Hair' is one of Leighton-Jones' best-loved and most successful images. It was reproduced in a number of formats including a lithograph printed on canvas, published in the 1970s. It was produced as an unlimited edition and best estimates suggest it sold in excess of a million copies
