Content note: Ethnic slur ('Jap') in the title; the Japanese enemy is drawn as a bucktoothed rat in a trap. This object is shown as it was published. Why
"Jap Trap": Material Conservation (Douglas Aircraft poster)
A bucktoothed rat in round glasses, a rising-sun cap flying off his head, is caught by the jaws of a mousetrap marked 'Material Conservation'; the title reads '"Jap Trap".' Saving materials on a factory floor is staged as a trap for a verminous Japanese figure, so the slur and the animal do the arguing.
