This button is likely tied to a milk advertising campaign. In the 1940s, federally subsidized milk advertising began under the Works Progress Administration (WPA), part of FDR's New Deal. The WPA commissioned artists to paint posters advertising milk, which had a dual purpose -- to employ artists and to increase the demand for milk, which, in turn, would help dairy farmers. Since then, milk campaigns have been going strong with catchy slogans such as "Milk Matters", "Milk Life", and "Got Milk?".
