BBC News - Original Kermit the Frog puppet given to Smithsonian:
The original Kermit the Frog has been donated to the Smithsonian's National Museum of American History in Washington.
The muppet was donated by creator Jim Henson's widow Jane, along with nine other characters from the 1955 TV show Sam and Friends.
Some of the other muppets in the collection include early versions of Cookie Monster and Oscar the Grouch.
Henson's oldest puppet, Pierre the French Rat, was also donated.
Jane Henson said the original characters provided five minutes of fun each night after the local news where they mostly mimed to popular music.
