A collection of photographs of Marilyn Monroe, spanning her lifetime from obscurity to Hollywood sex goddess, is being offered for sale this month.

The collection captures Monroe in all her manifestations -- playful, sexy, innocent, insecure and anguished -- as chronicled by some of the biggest names in photography, including Richard Avedon and Bert Stern.

The more than 100 images will be sold at Christie's auction house in three sessions on December 16-17. They are expected to bring from $811,000 to $1.1 million. See more image at the Christie's site.
