Richard Polsky’s new book, I Sold Andy Warhol (Too Soon) (Other Press, $23.95), hits stores on Sept. 15, 2009. Via events surrounding the auction sale of his Warhol "Fright Wig" self-portrait, Polsky chronicles the "highly loopy and irrational culture of collectors and dealers" (New York Observer) during the art-market booms and busts of the last 25 years. Here, we present an excerpt from Chapter 11, It’s All in the Timing, which relates a bit of market history of one of Wayne Thiebaud’s best-known paintings.
