Actor Sylvester Stallone has donated props from his Rocky films to the Smithsonian's National Museum of American History in Washington DC.
Stallone said the Rocky series "represents a journey of hope"
The memorabilia includes a boxing robe from the first Oscar-winning film in the series and a set of boxing gloves from the second.
"I knew I was getting old, but I didn't think I would be with the dinosaurs so soon," joked the actor.
Stallone is currently promoting Rocky Balboa, the sixth film in the series.
A pair of red, white and blue boxing shorts from Rocky III also forms part of the donation.
The props will be displayed in the museum's Treasures of American History exhibition, alongside a cornet played by jazz star Louis Armstrong and one of singer Ray Charles's tuxedos.
The exhibition itself will be housed at the National Air and Space Museum while the Museum of American History is closed for renovation.
Curator Dwight Bowers said the memorabilia "could not be better in conveying the interplay of sports and entertainment in American film history".
The original Rocky, released in 1976, told the story of a small-time boxer from Philadelphia who gets a shot at the world heavyweight title.
Rocky Balboa, which Stallone also directs, is released in the US on 20 December.
