What is on the pixies album wave of mutilation artwork?

The artwork for the Pixies' album "Wave of Mutilation" features an image of a young woman with a scarred face and a noose around her neck, surrounded by flowers. The image is a cropped version of a painting by Sir Frank Dicksee called "The Tragic Muse". The original painting depicted the Greek goddess Calliope, the muse of epic poetry, holding a tragic mask and a quill pen. In the Pixies' version, the mask has been replaced by the noose, and the quill pen by a knife. The image is meant to represent the dark and tragic themes of the album's songs.
