Evelyn Nesbit!
Or at least, the face that caused a big fat millionaire to kill a hot young architect in a spectacular crime of passion. Such is my understanding of the case.
It's interesting to note that in film representations of dear little Evelyn, Joan Collins stands along side Elizabeth McGovern (Ragtime). So, apparently, there is considerable disagreement regarding how this femme fatale is to be represented.
To get a look at how Ms. Collins looked while portraying Evelyn, check out the (gasp!) Joan Collins Webpage.
Even crazier is a must-visit site about Stanford White's decadent and notorious "Pie-Girl Dinner". It includes as well a brief account of trial, and tons of spiffy old-time photos.
