Could This Be Love (Abel Ferrara, 1973; photographed by Jon Rosen)
Tender sleaze. This shot's from the lesbian threesome scene in Could This Be Love, a little bit of softcore "to wake up the audience," scored to the Stones' "She Smiled Sweetly." If you look really closely, you can see that it's a woman kissing another woman's back.
Since the beginning, Ferrara has been getting his art and his exploitation mixed up. Or, even more accurately: in the beginning, Ferrara thought that he could prove that exploitation could be "art," or at least arty (Ms. 45), but then he realized that art itself was exploitation (Dangerous Game).
