Flat File originally from the National Geographic Museum in Washington, DC. It must have been used in the offices there. It came with old Nat Geo slides and pictures, which you can have with it if you are interested.
Casters have been added to the bottom of the flat file so it can be rolled around. The outside is a bit rough with some dents and scratches, but it is a great piece.
The table is 41″ × 29″ × 18 1/2" tall.
Thanks for looking.
