Residents of a town in central Norway are eager to learn what's inside a mysterious package sealed since 1912.

The nearly seven-pound package was left behind by Sel's former mayor Johan Nygaard with the disclaimer that the parcel "be opened in 2012," the Local reports. The town plans to open the sealed and bound package on Friday.

It has survived two world wars and reportedly was almost thrown out twice during clear-out operations through the decades.

Mayor Nygaard kept the package himself until the 1920s, when he reportedly transferred it to council authorities for safe-keeping. It is now held at the Gudbrandsdal Museum.

"It's going to be incredibly exciting," museum worker Kjell Voldheim told newspaper VG. "We have fantasized a lot about what it might contain."

Voldheim says some speculate the package contains historical documents, and the town council hopes it contains a "sheaf of oil shares" that could benefit the community.

"Or maybe it's the Blue Star diamond from the Titanic, which sank in 1912," Voldheim joked.
