Okay the big tour de force for the commonality of what constitutes facial attractivness was:
Michael R. Cunningham, Alan R. Roberts,Anita P. Barbee,Perri B. Druen, Cheng-Huan Wu "Their Ideas of Beauty Are, on the Whole, the Same as Ours: Consistency and Variability in the Cross-Cultural Perception of Female Physical Attractiveness " Journal of Personality and Social Psychology. Vol. 68 (2) February 1995, pp. 261-279. American Psychological Association
I thought this study also showed that exposure to faces of diffrent races increased attractivness ratings, I was wroung. That information actually when I started e-mailing around was something I must have picked up in my conversations with on of my advisors. He said it was ancedotal but talked about but he couldn't think of a specific study. So I this is what I got. Sorry about that.
I don't think that mix up harms my point that facial attractivness as a sexually selected signal stays pretty constant across cultures and that minor variations are insignificant and probably totally accidental and not under direct selection of any type.
