I have no idea why this one would stick in my mind so well after all this time. It depicts Mary Magdalene, not quite in the biblical tradition, and is titled Mary Magdalene in the Cave.

This second image is titled Young Woman with Morning Glories in Her Hair. The hair in this one is more of a soft, shiny auburn colour.
