Farrah Fawcett's longtime companion Ryan O'Neal will donate the swimsuit and other items to the Smithsonian's National Museum of American History on Wednesday. A 1976 poster of Fawcett in the dampened red swimsuit sold millions of copies.
Also going to the Smithsonian are Fawcett's copies of scripts for the first season of Charlie's Angels and a 1977 Farrah Fawcett doll.
The items will be part of the museum's popular culture history collection.
Fawcett died in 2009 at the age of 62 after battling cancer.
