It's a mold for a loaf of Vienna bread. The wire bails were to keep the mold together when it rose during baking. A similar mold was also used to make "boardinghouse bread" or "lodgers bread." The idea was that the bread could be sliced very thinly (therefore the loaf lasted longer) by cutting along the ridges.

It's also the Iron Man's pencil box.
