A picture found amongst a pile of papers in a Las Vegas garage sale has been attributed to Andy Warhol. The sketch was thought to have been produced by Warhol when he was 10 or 11 and being looked after by the vendor's aunt in the 1930s, which would make it the earliest known work by Warhol.
The canny purchaser from the UK paid $5 (£3) for it and has had it valued at $2million (£1.3m).
The subject of the coloured portrait is William Hopalong Cassidy a cowboy character who first appeared in short stories and novels in 1904. His popularity grew when the first of 66 movies came out in 1935. In the early films he was played by William Boyd who is probably the face in the painting.
