Thirteen pieces of artwork have been stolen from an exhibition in Linz.
The artworks were lithographs by the artist Bernhard Gwiggner and had been done on folded paper, a medium called leporello.
They were on show at the ICON-Galerie in Linz as part of the Dao ji jing exhibition where 701 pieces of work were being presented to the public.
The organisers of the exhibit only noticed that thirteen items had gone missing when they took the exhibit down.
Police say they believe the theft took place in daylight whilst the exhibition was open but they could not confirm if it was a single thief or a group working together.
Regardless, it is difficult to know how much the stolen artworks will sell for since their value would probably decrease once separated from the larger collection.
