Miss Piggy to join Kermit the Frog in Muppet collection at Smithsonian museum on National Mall

Miss Piggy is finally joining her love, Kermit the Frog, in the Smithsonian Institution's collection of Jim Henson's Muppets, and Bert and Ernie will have a place in history, too.

Henson's daughter, Cheryl Henson, is donating more than 20 puppets and props Tuesday to the National Museum of American History, including Miss Piggy and the Swedish Chef from "The Muppet Show," Bert and Ernie from "Sesame Street" and Boober Fraggle and Travelling Matt from "Fraggle Rock."

Many of the puppets are the first constructions of the characters.

The museum currently holds Oscar the Grouch, Kermit and the cast of Henson's early TV show "Sam and Friends." The collection includes the original Kermit the Frog creation, as well as the more famous Kermit from "Sesame Street" and "The Muppet Show."
