人體好像工廠 (Human body is like a factory), Shanghai Xueyou Books and Art Club, 1933
In the 1930s, people were trying to understand the human body and how to depict its inner workings. One theory was that the body is like a factory, which is visible in the top image of this poster. The arms appear as winches and cranes, lungs as bellows, and the liver as a furnace. The brain is depicted as an office space, the desk jobs, to illustrate where the executive functions of the body are.
