Photos of Marilyn Monroe which were supposed to go on exhibit at Prague Castle have been stolen, along with display cases and mannequins that were also to be included in the event.

The items were collected by Italian museum creators last year in tribute to the 50th anniversary of Monroe’s death and included the star’s shoes, clothing, and diaries. Those in charge of the exhibition have not decided whether they will go on with the Prague show; it’s scheduled to move on to Tokyo soon, however.

Monroe was one of the most photographed women in the world at the height of her fame; several pictures of her taken by friend and makeup artist Allan Snyder were auctioned off last year for a pretty penny. The movie star and beauty icon still holds our fascination, even decades after her death, and the PR firm handling the exhibition hopes to catch whoever nabbed the items so that they may be shared with the world.
