GRAND JUNCTION (AP).- A Colorado Goodwill store is auctioning off a purported lithograph of a Salvador Dali work that it received from a mystery donor.
But the Grand Junction shop says it doesn't plan to verify the work's authenticity.
A customer at the store recently pointed out the signature on the print of "The Discovery of America by Christopher Columbus," which was numbered 168 out of 300.
Manager Bill Atwell told Denver's KMGH-TV he doesn't know who donated the piece.
Atwell says the store is "here just to raise money for our programs," and it isn't going to pay an expert to determine if the work is authentic. He says the store will instead let people bid for the piece and determine its value on their own.
As of Monday afternoon, bidding had climbed to $550.
The original painting is in the Salvador Dali Museum in St. Petersburg, Fla.
