Black Swan jewelry box, autographed by Natalie Portman, included in this year's Screen Actors Guild Awards Ceremony Auction

Proceeds from the Screen Actors Guild Auction benefit the SAG Foundation's efforts to promote children's literacy. One popular item on a recent auction was a Black Swan jewelry box.

The black jewelry box has a red velvet interior and plays Swan Lake when opened. Natalie Portman, star of the popular film of the same name, autographed the box next to her photo, which appears against a white background on its lid.
