While sorting out a collection of particularly dusty books and documents, UMAM D&R came across a sealed folder whose kaleidoscope of stains and smudges led one to wonder what could possibly be inside, and from what era did its forgotten contents hail.

How is it that after decades of existence not a single person ever got curious enough to open it up? We could hardly wait to see what kind of window into the past was waiting to be seen.
