It always seems that when you misplace something, it will wind up in the darndest places—behind the couch, in the produce drawer of the refrigerator, or in the case of a lost Disney film, Norway.

In a plot line straight out of The Librarians, a team of archivists were conducting an inventory at the high security bunker operated by Norway’s National Library in Mo i Rana, near the Arctic Circle, when they made an incredible discovery: a 1927 Walt Disney cartoon, which was long-considered to be lost.

The cartoon is an almost complete version of the 1927 short, Empty Socks, starring Oswald the Rabbit, a precursor to Disney's more famous animorph, Mickey Mouse, according to Agence France Presse. The film, which was authenticated by Disney cartoonist David Gerstein, is Disney’s first Christmas film.

Before the discovery, only 25 seconds of the 5 minute 30 second-long film were thought to exist, held by the Museum of Modern Art in New York. Approximately 25-30 seconds are still missing, but the Norwegian film is the most complete version now known.

"At the beginning, we didn't know it was a lost cinematographic treasure," said Kjetil Kvale Soerenssen, an archivist at the library, speaking to Agence France Presse. "The film was in two reels which weren't clearly labeled." The film has now been digitized and a copy sent to The Walt Disney Company.

Empty Socks is one of nine Oswald cartoons made by Walt Disney when he worked at Universal. He left in 1928 to form his own company where he created Mickey Mouse, while Oswald stayed with Universal, starring in films throughout the 1930s and the early 1940s.

Disney reacquired Oswald in 2006 and the lucky rabbit starred alongside his one-time usurper, Mickey Mouse, in the 2013 cartoon, Get a Horse.

This is the second Oswald film to be discovered in recent years. Hungry Hobos was found in the U.K. in 2011.
