A California woman says the painting she bought for $3.1 million at an Upper East Side gallery is nothing but a bunch of worthless splatters.

Frances Hamilton White filed suit in Manhattan federal court against the former Knoedler Gallery, claiming it sold phony art to unsuspecting buyers.

The suit says she bought a painting purportedly by Jackson Pollock called “Untitled 1949” in 2000.

White tried to sell the painting in 2011 through Christie’s, but the auction house said it wasn’t authentic.
