WWII Japanese Aircraft Carrier Table Medal

An iron, single sided table medal that has the relief image of a Japanese Aircraft carrier and its superstructure. The medal is approximately 1 5/8 inches in diameter. It is contained within a wooden box that has a circular recessed compartment but, since the medal does not quite fit into that recess, the box is possibly not the original container. The lid to the box exhibits some damage in that it is missing one side.
