Janine Antoni. "Lick and Lather," detail, 1993. 7 soap and 7 chocolate self-portrait busts, 24 x 16 x 13 inches each. Collection of Jeffrey Deitch, New York. Photo by John Bessler. Courtesy the artist and Luhring Augustine.

"I wanted to work with the tradition of self-portraiture, but also with the classical bust. I had the idea that I would make a replica of myself in chocolate and in soap, and I would feed myself with my self, and wash myself with my self. Both the licking and the bathing are quite gentle and loving acts, but what's interesting is that I'm slowly erasing my self through the process. So for me, it's about that conflict, that love/hate relationship we have with our physical appearance, and the problem I have with looking in the mirror and thinking, 'Is that who I am?'"
