A version of the dress, made by the original designer Bill Travilla for Monroe for tours and exhibits, is also among the items up for sale, along with her hand-annotated script for the film.

Also in the auction are Monroe's personal childhood photographs 15 costumes she wore in films, including dresses from Gentlemen Prefer Blondes and How to Marry a Millionaire.

The exhibit at The Paley Center for Media will also feature large format photographs of Monroe by fashion photographer Milton H. Greene, who was a friend of the actress.
