AceShowbiz - Another pair of Judy Garland's iconic ruby red shoes from "The Wizard of Oz" are going up for sale, with a price tag of $6 million. The movie props, which Garland used for dance scenes in the beloved 1939 movie, will be sold by memorabilia dealers at Moments in Time.

Dealer Gary Zimet has owned the slippers for 18 years. They previously belonged to a Tennessee teenager, who reportedly won them in a 1940 film contest. "They are the holy grail of movie memorabilia," Zimet says of the shoes, which are adorned with rhinestones on the bow and assorted beads and jewels.

There are a few other pairs of the ruby slippers, which were made as props for the movie. Directors at the Smithsonian National Museum of American History received one pair from an anonymous donor in 1979 and late actress and collector Debbie Reynolds owned another pair.

The slippers on display at the Smithsonian will be preserved thanks to a 2016 Kickstarter campaign.

Directors at the National Museum of American History launched the initiative to save the shoes from deterioration. They reached their $300,000 goal in October, 2016, after over 5,300 people from 41 countries offered up donations for the restoration project.

The funds raised were used to help experts conserve the shoes and allow museum bosses to purchase a state-of-the-art display case designed to protect the slippers from environmental harm.
