Nice vintage Superman Metal Lunchbox with no Thermos.  Copyright 1978 DC Comic  Aladdin Industries Incorporated, Nashville, Tenn. It has the Thermos holder, but no thermos.  Nice condition for it's age, but the paint is worn off in a few places.  Latch works and it opens and closes as it should.  Measures 8" x 7" x 3 3/4".  The lunchbox is metal, but the handle is plastic.
