A Norwegian art gallery reportedly lost a Rembrandt etching worth up to $8,600 in the mail while trying to save money on shipping and insurance costs, the gallery’s chief said.

Reuters reports that the Soli Brug Gallery in Greaaker, roughly 50 miles south of Oslo, purchased a copy Rembrandt’s “Lieven Willemsz, van Coppenol, Writing-Master” from around 1658 from a British dealer – only to see it lost in the Norwegian postal system.

"Using a courier or special insurance is quite expensive so we have used regular mail until now," Ole Derje, the gallery's chairman told Reuters.

The gallery, which is displaying works by Dürer, Rembrandt and Dali, received notice to pick up the package but when he went to collect it, it was nowhere to be found, Derje said.

Derje declined to name the seller, citing confidentiality concerns.

"We are sorry that this has happened,” said Hilde Ebeltoft-Skaugrud, a postal service spokesman. “We have advised him to use a more appropriate form of mail when sending items that are worth as much as this with the appropriate insurance connected.”
