A pair of the iconic ruby red slippers from “The Wizard of Oz” is going up for auction with an estimated price of $2 - $3 million. California auction house Profiles in History said the slippers -- one of four known surviving pairs made for the 1939 movie -- are believed to have been worn by Judy Garland's Dorothy when she clicks her heels to return home to Kansas near the end of the film. The slippers will be auctioned on December 16 in Los Angeles as part of a Hollywood memorabilia sale. Profiles in History owner Joe Maddalena said he was expecting bids from around the world. “This is the most important film prop in the world. There is nothing more famous,” said Maddalena. “They are one of the greatest pieces of pop culture in existence.” One of the pairs of slippers used in the “Wizard of Oz” is on exhibit at the Smithsonian Museum in Washington, one is in private hands and another was stolen from the Judy Garland museum in Minnesota.
