Backs of women’s heads: A trio of similar covers

There are a heaps of books that feature the back of a woman’s head on their covers, but I was surprised to come across three pairs (or trios) of covers using the same image:

The Piano Teacher by Janice Y. K. Yee and Silk by Penny Jordan both feature the same image from the Condé Nast Archive—and it’s interesting that there’s an Asian connection between the two books, yet an image of a blond Causasian woman was chosen for their covers...

Edited to add:
Thanks to TinEye, I found a third cover to match the two above: As Esquinas do Tempo (which literally means The Corners of Time in Portuguese) by Rosa Lobato de Faria.

The titles to The Good Mother by Sue Miller and The Gallows Girl by Melanie Gifford conjure up fairly opposite images in my mind but feature the same woman on their covers...

Edited to add:
Sarah, who maintains the Reusable Cover Art page, pointed out a third cover featuring the same woman: The Various Flavors of Coffee by Anthony Capella. I gotta say, I really don’t like this one!

Finally, another unlikely pair is The Gospel of Judas by Simon Mawer and Look Homeward Erotica by the Kensington Ladies’ Erotica Society!
