A pair of ruby red slippers worn by Judy Garland in ‘The Wizard of Oz’ has been sold at auction for $28 million, marking a new record for movie memorabilia. Initially expected to fetch only $3 million, the slippers, one of four surviving pairs, became the ‘Holy Grail of Hollywood memorabilia’ following a month of online bidding. The sale coincides with renewed interest in the musical, spurred by the recent release of the prequel ‘Wicked.’
