Roughly 6" x 8 1/2" for the cover. Good to Very Good shape with not too much wear, it is forming brown age spots inside. Rare and incredibly hard to find kind of item. Former keepsake of a woman who worked at the shipyard which built it from the 30's through the 70's and opportunities like this are not found every day. Or evening. This vessel was prominent in the early jet fighter age and helped stare down the Soviet Union during the Cold War, giving it a significant place in history.
