Who is the woman who appears on the cover of This Mortal Coil's "It'll End In Tears"?

It's a young lady called Pallas Citroen.

She is rather hard to track down as there is a Citroen car called the Pallas and that tends to come top of the Google searches!

gentlegiant17 -- Do you actually have a name, as I'm finding the following:

The single "Kangaroo" (AD 410) was issued just prior to the album It'll End In Tears (CAD 411). The striking cover photographs of model Pallas Citroen were originally intended for Modern English's Ricochet Days, but the group rejected them.

The selection of cover versions on the album included material by Tim Buckley, Gene Clark, Tom Rapp, Judy Collins and Colin Newman. Prior to the release of the album, a limited edition 10-inch single (BAD 608) was issued coupling striking interpretations of Van Morrison's "Come Here My Love" and Talking Heads' "Drugs." Model Pallas Citroen became the cover star once again after actress Maria Schnieder rebuffed Ivo's overtures.
