1980. Great metal box by King Seeley Thermos Co.. Overall very good for much less then normal wear and signs of age. One side has large shot of Perseus with Owl. This side shows a little bit of surface raised areas but it is smooth and not chipping. Other side is in beautiful shape and has a great picture of Perseus fighting the Kracken on Pegasus. Interior is very clean and has large child's name in ink on upper lid.
