In May 2006, an exhibit called Muppets and Mechanisms opened at the Smithsonian. The exhibit, divided into three displays at the American History Museum, featured nine puppets from the original Sam and Friends show; a display of characters puppeteered by Jim Henson including Dr. Teeth, Rowlf the Dog, Kermit, and Jim; and animatronic figures and mechanisms from The Dark Crystal and Emmet Otter's Jug-Band Christmas. Jane Henson opened the exhibit.
Jane Henson, on behalf of the Jim Henson family, donated 10 of the original Sam and Friends puppets to the Smithsonian’s National Museum of American History on August 25, 2010. These included the original Kermit, Pierre the French Rat, Yorick, Mushmellon, Sam, Harry the Hipster, Chicken Liver, Icky Gunk, Moldy Hay, and Professor Madcliffe.
A traveling Smithsonian exhibit of Muppets opened Sept. 24, 2010 at Chicago's Museum of Science and Industry.
Jane Henson stated in 2010 that the family plans were to donate more puppets to the Smithsonian in the future. Those plans came to fruition three years later, when Cheryl Henson donated 20 more Muppet puppets and props to the National Museum of American History on September 24th, 2013 (Jim Henson's 77th birthday). Among the additions were Ernie, Bert, Elmo, Count von Count, Prairie Dawn, Miss Piggy, Fozzie Bear, Scooter, J. P. Grosse, Red Fraggle, Boober Fraggle, Uncle Traveling Matt, and Wilkins; as well as early puppet builds of Grover, Cookie Monster, and Rowlf the Dog.
