Another top auction item was a Winkie guard costume from “The Wizard of Oz,” which sold for $115,000. In December, Profiles in History auctioned Bert Lahr’s original Cowardly Lion costume for a record-breaking $805,000. Many of the buyers were baby boomers looking to own a piece of their youth, said Joseph Maddalena, owner of Profiles in History. Maddalena, 46, said boomers like him are “buying into nostalgia. They’re buying their childhood.” Christopher Reeve’s costume from “Superman” and the creature from “Alien” helped Calabasas Hills-based Profiles in History net more than $2 million in its latest auction. Profiles in History auctioned off more than 700 items Thursday, including costumes, scripts and posters from classic Hollywood films. Superman’s iconic blue and red leotard sold for $115,000, while the “Alien” creature suit went for $126,500. The latex and gauze creature costume, designed by H.R. Giger and used in some scenes of the 1979 film directed by Ridley Scott, was mounted in “attack mode,” according to the auction house. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
