One of the most iconic pieces of Hollywood film history is now up for grabs. The ruby red slippers made famous by Dorothy Gale in The Wizard of Oz will be auctioned off on December 16 by California’s Profiles in History auction house. “This is the most important film prop in the world,” said Profiles in History owner Joe Maddalena. “There is nothing more famous. They are one of the greatest pieces of pop culture in existence.” One of the four known surviving pairs of slippers made for the 1939 film (another set are displayed at the Smithsonian’s National Museum of American History), they are believed to have been worn by Judy Garland and expected to fetch between $2 and $3 million.
