I'm trying to find a value for a Cindy Sherman photo of cigarette butts, signed Cindy Sherman 1988/94. Any ideas on where to look?
All the big auction houses have websites where recent auctions are listed, and you could contact them for a valuation.
She is probably represented by a gallery in NYC, that sells current and past works. Here is a website that has hammer prices but you have to sign up. It may be free I didnt read the details.
Here is a link that might be useful: ArtPrice
It may be Gagosian Gallery. I found one price of $6500 for a print in 2007, but it was a self portrait from the 70s. I don't imagine the non-portraits command as much.
I found the photo online. It's called Untitled (Queen of Hearts) and last sold for around $1400.
