There’s been no shortage of memorabilia from the Superman film franchise starring Christopher Reeve, but a new item being offered by Julien’s Auctions could be considered a cut above other film props. It’s a cape worn by Reeve for sequences in the Superman movies, and it could fetch up to $40,000 at auction.

The cape appeared in 1978’s Superman: The Movie, 1980’s Superman II, and possibly 1983’s Superman III. According to Julien’s Auctions, the trademark red cape was used to film Reeve while he was mounted on a wire harness, for both blue screen and front projection work, to make it appear as though he was flying. Slits in the fabric accommodated the wires. There are also pockets at the bottom of the cape so rods could be inserted to make it seem as though it were flapping in the air.

The auction is currently taking bids and runs through July 17. Julien’s Auctions estimates the cape could sell for between $20,000 and $40,000. The auction house is also offering a space suit from 1968’s 2001: A Space Odyssey ($200,000 to $300,000), a Pontiac Firebird Trans Am used for appearances as KITT from Knight Rider ($100,000 to $200,000), and hazmat suits worn by Bryan Cranston and Aaron Paul in Breaking Bad ($500 to $2000).
