The ruby slippers were not built to last beyond the film's final take, but the museum is responsible for ensuring that they survive for generations to come. Over the years, the shoes have aged and their color had faded -- a process begun on set with exposure to the intense brightness and heat of studio lights. In 2016 the museum launched a major preservation project funded by a Kickstarter campaign that garnered contributions from 6,000 fans. |
