Saving Dorothy's ruby slippers: $300K Kickstarter aims to preserve Smithsonian's beloved shoes

It will take more than three clicks of the heels to preserve the ruby slippers that whisked Dorothy back to Kansas at the end of The Wizard of Oz.

It will take more than three clicks of the heels to preserve the ruby slippers that whisked Dorothy back to Kansas at the end of The Wizard of Oz.

The slippers, which for more than 30 years have been one of the most beloved items at the Smithsonian's National Museum of Natural History, were crafted almost 80 years ago by the MGM Studios prop department. Like most movie props, they weren't built to last. Now, the frayed shoes aren't even ruby-coloured anymore — they're more like a dull auburn.

On Monday, the Smithsonian asked the public to help save the slippers, launching a Kickstarter campaign to raise $300,000 (all funds US). In addition to keeping the shoes' colour from deteriorating further, the money will go toward a technologically advanced display case that will preserve them for future generations.

The Smithsonian's museums are federally funded, but the institution frequently solicits private and corporate contributions for major projects that its budget doesn't cover. This is the Smithsonian's second Kickstarter campaign. In 2015, the National Air and Space Museum raised $700,000 through the crowd-funding site to preserve the spacesuit that Neil Armstrong wore when he walked on the moon.

"This particular pair of ruby slippers really belongs to the American people, and so we thought as we sought support that we would invite the public to join us on this journey to help preserve them for the next generation," said Melinda Machado, a museum spokeswoman.

If the Kickstarter campaign is successful, the slippers will be the second-most-researched item in the museum's collection, behind the flag that inspired Francis Scott Key to write The Star-Spangled Banner, said Richard Barden, the museum's head of conservation.

The shoes are the most recognizable prop for the beloved 1939 musical, their deep red hue dazzling audiences when the movie made its dramatic transition from black-and-white to Technicolor. They have been on near-constant display since they were anonymously donated to the museum in 1979.

Complicated preservation needed

Their age is showing, and preserving them is more complicated than it might appear. The slippers contain a dozen different materials. The sequins are made of gelatin with a primitive plastic coating, and many are no longer red because the coating has flaked off, in part because of decades of exposure to light and moisture. The undersides of the sequins, or portions that did not have direct exposure to light, have retained more of their colour.

The shoes also include glass beads and red felt on the soles that was used to muffle their sound when Judy Garland wore them during dance sequences.

The pair is also mismatched: One shoe is wider than the other, and there are other subtle differences in their shape. Each has Garland's name written inside.

As of the morning of Wednesday, October 19, 2016, donors to the Smithsonian's "Conserve Dorothy's Ruby Slippers" campaign had pledged about $141,000 on Kickstarter. Donations start at $1 and, depending how much they give, contributors can receive rewards including T-shirts and tote bags created by costume designer William Ivey Long. (Kickstarter)

The museum will research the ideal conditions for the various materials that make up the shoes. The new case is likely to contain a gas other than oxygen, with controls on temperature, humidity and barometric pressure, Barden said.

"That case becomes very expensive to build, and we want to build one that will be efficient and low-maintenance so we're doing the best for the slipper and keeping our costs as low as possible," Barden said.

As of Wednesday morning, donors had pledged about $141,000 on Kickstarter. If the museum does not reach its $300,000 goal in 30 days, no one will be charged.

Donations start at $1 and, depending how much they give, contributors can receive rewards including T-shirts and tote bags created by William Ivey Long, a Tony award-winning costume designer.

5 Things to Know about the Smithsonian's ruby slippers

  • THEY'RE NOT THE ONLY PAIR: At least seven pairs of slippers were made for the movie, and four pairs are known to exist. The Smithsonian's pair was donated anonymously in 1979 after being sold at auction in 1970. Two other pairs are owned by private collectors, including a pair purchased by Leonardo DiCaprio and Steven Spielberg for display at the Academy Museum of Motion Pictures, which opens next year in Los Angeles. A fourth pair was stolen from the Judy Garland Museum in Grand Rapids, Minnesota, in 2005, and remains at large.
  • THEY'RE MISMATCHED: One shoe is wider than the other, and there are other subtle differences in their shape and construction. Each has Garland's name scrawled on the inside. One is marked as "#1," the other as "#6."
  • NO RUBIES: The shoes are made from about a dozen different materials, including wood pulp, silk thread, gelatin, plastic and glass. Most of the ruby colour comes from sequins, but the bows of the shoes contain red glass beads. They began as ordinary shoes that were dyed red, and a netting with the sequins was fitted for them and sewn on. They have felt on the soles to muffle their sound for dance sequences.
  • NOT MADE TO LAST: The shoes are nearly 80 years old, and like most movie props, they weren't built to last. During their time at the museum, the colour has faded significantly from exposure to light and moisture. Some of the sequins have no red plastic coating left and are no longer translucent.
  • COSTLY PRESERVATION: If the Smithsonian successfully raises $300,000 US, most of the money will go toward scientific research and construction of a special case that will keep them from deteriorating further. The shoes will also be cleaned, but nothing will be done to enhance their colour or repair them with newer materials.
