Nearly 500 items from Stallone’s personal archives are being sold, including costumes, props, scripts, notebooks and other memorabilia from the actor’s biggest films, including the “Rocky” and “Rambo” franchises, “Cliffhanger”, “The Expendables” and “Demolition Man,” Julien’s Auctions said yesterday.

Highlights include Stallone’s boxing gloves from “Rocky III” with an estimate of US$10,000-US$20,000, as well as handwritten notebooks about the first four “Rocky” films, priced at US$40,000-US$60,000.

“Rambo” fans are being offered a collection of knives from the first three films, priced US$10,000 to US$20,000 each, as well as a headband worn by Stallone in “Rambo: First Blood Part II” (US$8,000-US$10,000) among other memorabilia.

“He’s a sports guy, that’s what he represents, sports and hard graft and people can relate to that,” said Martin Nolan, executive director at Julien’s.

“That’s why he’s so collectable, and people have had very little opportunity to own anything from his life and career until now.”

Born in New York in 1946, Stallone found fame with 1976 Oscar-winning boxing film “Rocky”, soon becoming one of Hollywood’s biggest action movie stars.

Asked why the actor, now aged 75, was selling the items, Nolan said: “He’s relocating and selling his house, so it’s the perfect time for anyone to downsize.

“We expect a huge response because people have pent-up demand for iconic items like these – authentic items coming directly from the man himself.”

Other items for sale include posters, the boxing mouth guard worn by Stallone in “Rocky”, a costume designed by Gianni Versace for “Judge Dredd”, and a “Cliffhanger” arm sculpture.
