UP FOR GRABS: Heritage Auction Galleries begins one of its biggest auctions of the year today when collector Charles Martignette’s collection of illustrations hits the blocks. Martignette was an eccentric collector who stashed away more than 4,000 pieces. One of the highlights is a Joseph Christian Leyendecker oil painting (right) that became a Saturday Evening Post cover. It’s expected to go for $50,000 to $70,000 in an auction that could yield as much as $20 million says the Associated Press.

The festival concludes with performances on Thursday and Friday.
