A Superman tunic worn by Christopher Reeve in the blockbuster 1978 movie is expected to make in excess of $50,000.
It's among the highlights of a memorabilia auction at Nate D Sanders on November 19.
The auction house told Comicbook.com: "The lanky 6'4" Reeve refused to wear a muscle suit under the costume and trained with bodybuilder and Star Wars actor Dave 'Darth Vader' Prowse for several months to prepare for his role.
"Academy Award-winning costume designer Yvonne Blake designed the Superman costume, which was constructed by Noel Howard for London-based Bermans and Nathans."
The tunic is constructed from a stretchy nylon fabric and displays the iconic "S" symbol on the chest.
A complete suit worn by George Reeves (no relation) in the 1950s Superman TV series made $230,400 at Profiles in History earlier this year.
A pair of suits worn by Will Smith and Tommy Lee Jones in Men in Black 3 will be offered at tomorrow's auction with an opening bid of $20,000.
Both were used onscreen and each displays the name of the star on the inner label.
The franchise is among the most successful in recent years, grossing $1.6bn worldwide - with this third instalment pulling in $625m.
