KNOXVILLE, Tenn. -- The son of actress Debbie Reynolds says her big Hollywood memorabilia collection, including the red slippers from "The Wizard of Oz," is set to be auctioned by June.

Todd Fisher, whose mother starred in "Singin' in the Rain," said last week that Christie's in New York will manage the sale.

Reynolds, 78, amassed the estimated $50 million collection over decades. It also includes the fur coat worn by Orson Welles in "Citizen Kane" and Marilyn Monroe's subway dress from "The Seven Year Itch."

Reynolds announced in 2004 she would relocate her collection from Las Vegas and Hollywood to Pigeon Forge, Tenn. But Fisher says a museum project there had to file for bankruptcy protection last year and the collection must be sold to satisfy creditors.
