CHICAGO — University of Chicago officials are puzzled by a mystery piece of mail seemingly linked to the Indiana Jones movie series.
The package contained a replica of the journal from the "Raiders of the Lost Ark" film – and no explanation.
University officials turned to Tumblr for answers.
Admissions counselor Grace Chapin says one theory is that it's an "alternate reality" game where players plant clues for others.
Officials with Lucasfilm, the studio that made the movies, say they weren't responsible for the package.
University officials say they haven't decided what to do with the journal.
