A pair of ruby slippers worn by Judy Garland in The Wizard of Oz have been stolen from a museum in Minnesota.
Four sets of shoes were used in the film
The pair, insured for $1m (£560,000), is one of four sets used in the film.
The slippers were taken at the weekend when a thief entered the Judy Garland Museum in Grand Rapids through a window and broke into a display case.
As Dorothy in the 1939 movie, Garland wore the slippers as she clicked her heels and thought to herself: "There's no place like home."
Police Chief Leigh Serfling said: "There's not a whole lot of evidence. We're hoping that someone in the community has seen something."
The Judy Garland Museum had the slippers on loan from their owner, a Los Angeles man, for several weeks.
The museum is part of the Children's Discovery Museum in Grand Rapids, where Garland was born in 1922.
Museum director John Kelsch said the slippers were a "major attraction".
"It is our hope that the slippers can be recovered immediately," he said.
Another pair of ruby slippers was sold at auction for $666,000 (£412,000) in 2000.
