Santa Monica Auctions, located currently in the B-7 & C-2 spaces in Bergamot Station allegedly has some handsome James Rosenquist prints currently on view. I'm not certain of the screenprint above, titled For the Young Artist (1991), being one of them, but word in the studio is that there are some impressively large prints on display. The phone number to call for further information is: 310/586-9128, & the address is 2525 Michigan Avenue.
I've included one of the past highlights from the last auction, Andy Warhol's Mao, a screenprint from 1972. Apparently, the auction coming up on 11/12 will be their last one in this space, as the "C" building is being demolished to make way for the Metro train line.
