The Greenhalgh Family name is famous in the art world thanks to three of its members. First, there is Shaun, born in 1961, still living with his parents. He is what you would call a self-taught. He left school at sixteen and flunked out of the Royal Marines because he couldn't swim. The only job he held was as a shop clerk in a convenience store. No artistic education whatsoever. And yet, without him, this scheme would never have existed. He is the forger.
