See video here of the preview showing of the art collection of Huguette Clark, heroine of "Empty Mansions," at Christie's in New York. (I was not aware until today that the self-portrait by Huguette is among the items being sold.) This is just a preview show. More than 400 items will be on view and for sale in June. From a press tour on the first day of the show, CBS 2 New York's Tony Aiello reports: http://emptymansionsbook.com/video/. See the schedule of showings and sales at http://nbcnews.com/clark.
