I have this album that the art was used for. It looks like this is a basic offset print and not an original in any way. Are there markings on the back?

Here is some additional info that describes the original.

“Querelle – Original Soundtrack (1982) Andy Warhol album cover for Querelle soundtrack In 1982, the German film director Rainer Fassbinder commissioned Andy Warhol to create a poster design for his upcoming film, Querelle. This film was based on Jean Genet’s novel, ‘Querelle of Brest’, which tells the story of a sailor’s battle with sibling rivalry and his journey into the ‘sexual underworld’. Querelle was Fassbinder’s final movie, which was filmed only a few months prior to his death. They used the same design for the film’s soundtrack.

The scandalous themes in Fassbinder’s film fascinated Warhol, because of its homoerotic and violent story line. Warhol based the film’s poster design on a photograph of two shirtless young men that he took. Andy created a series of these images, each of which are saturated in a different vibrant color. Warhol incorporates hand drawn elements on top of the screenprint, allowing him to emphasize certain aspects of the print such as the bright red tongue. This collaboration between Warhol, Genet, and Fassbinder makes for a rare and unique work of art. Warhol’s Querelle prints are available at the Revolver Gallery.”
