I used to own this painting....Ahhhh I mean Spoon...I bought it on E-bay in late 2000 for about $500 and sold it in early 2003 for about $600.... Ohhh Well...
However 10Xs your money in 5 years is nothing to sneeze at...

The Bennet Bradbury (brother of Ray) story of how to make a market in Art is prototypical...John Moran Auction in Pasadena, CA got about 40 BB paintings consigned to them. They put 10 or so in each of their auctions and as the auctions progressed so did the prices...until then BB paintings were inexpensive...$600 would buy a 28 x36..now its about 4k or better.
