Unable to ascertain exact production dates. Early copies refer to Tom Hamilton as “Coach of US Naval Academy”, this one refers to him as “Former coach of...” Hamilton served as coach at Annapolis 1934-1936, and again 1946-1947. The 1946 and later editions came in a more colorful box, and the board design was changed to look more like a football field, so that would seem to indicate this edition is somewhere between 1937-1945. Box is heavily damaged, board is in nice shape, all cards and pieces appear to be present.
