Mondays are hard enough, let's try to be kind to each other. This 1927 work incentive poster reminds us that "Courtesy influences people in your favor. Rudeness turns them away." Employers used motivational posters like this one to encourage the behaviors they wanted to see in their staff. #BusinessHistory #LaborHistory #MondayMotivation #MotivationalPoster #GraphicDesign #1920s #Typography #PosterDesign [?: Randolph Collection, Archives Center]
