Efficient Workers Smithsonian WW2 production posters
'Efficient workers must be helped to attain even greater efficiency. And these objectives must be gained by methods that are in harmony with the principles of a democratic society; they cannot be gained by commanding them; they must be gained by supplying incentives that will induce voluntary action.'
S. D. Warren Company, a paper manufacturer, published a catalog of production-incentive posters in 1942, simultaneously supporting the cause and promoting their products.
