This comes from a prewar (and thus public domain) image of a poster presented by the Japanese National Archives. This poster (which didnt include the man's legs) was about safety, but I liked the odd way this man (with a creepy full head mask) was just putting one hand on his hip and one hand into the air. For the future, I decided to preserve it for posterity.
