Prints of the paintings?

John Bratby, an English painter prominent when the film was made, did the Gully Jimson paintings specifically for the movie. I would love to get copies -- if anyone knows if prints are on-sale, please leave word here on how to get them. Thanks!

The paintings include:
1. Adam and Eve (canvas, on Gully's houseboat)
2. Sal in the bathtub (canvas, at Hickson's house over the fireplace mantle)
3. Sal in the bed (canvas, the painting Sal has that Gully wants to sell to the Beeders)
4. Raising of Lazarus (wall mural painted in the Beeders apt.)
5. Last Judgment (mural painted on wall of about-to-be-demolished church)
