“The Smithsonian’s National Museum of American History closes next month for almost two years of renovations, but some of the museum’s most beloved artifacts — Dorothy’s ruby slippers, Kermit the Frog, ‘Star Wars’ droids — will reappear in the fall. Beginning Nov. 17, 150 objects from the shuttered museum will be part of the “Treasures of American History” exhibition at the Smithsonian’s National Air and Space Museum.”
