Hello,
World War II is a well-remembered world war. New weapons were introduced during this war, in fact, quite a lot. Some examples are the Browning Automatic Rifle (BAR), M1 Carbine Rifle, and Colt M1911 A-1.
The poster shown above can be summarized as a representation of a target (as though I feel it's a blimp) shooting for a target. During this war, there was and still is known today a War Production Board. This board regulated the production and allocation of materials and fuel during World War 2. I believe this poster, represents the necessity of mass production.
