Many of these artists found themselves drawn to the interwar movement known as Social Realism, which reflected the politics and socioeconomic views of a generation that had been drafted into WWI, only to dance through the Roaring 1920s and crash in the Great Depression. Important cities with significant black populations and important African-American art circles included Philadelphia, Boston, San Francisco and Washington, D.C. The WPA led to a new wave of important black art professors. Mixed media, abstract art, cubism, and social realism became not only acceptable, but desirable. Artists of the WPA united to form the 1935 Harlem Artists Guild, which developed community art facilities in major cities. Leading forms of art included drawing, sculpture, printmaking, painting, pottery, quilting, weaving and photography. In 1939, however, the costly WPA and its projects all were terminated. In 1943, James A. Porter, a professor in the Department of Art at Howard University, wrote the first major text on African-American art and artists, Modern Negro Art. Mid-century In the 1950s and 1960s, few African-American artists were widely known or accepted. Despite this, the Highwaymen, a loose association of 26 African-American artists from Fort Pierce, Florida, created idyllic, quickly realized images of the Florida landscape and peddled some 200,000 of them from the trunks of their cars. In the 1950s and 1960s, it was impossible to find galleries interested in selling artworks by a group of unknown, self-taught African Americans, so they sold their art directly to the public rather than through galleries and art agents. Rediscovered in the mid-1990s, they are recognized today as an important part of American folk history, and the current market price for an original Highwaymen painting can easily bring in thousands of dollars. In 2004, the original group of 26 were inducted into the Florida Artists Hall of Fame. Currently eight of the 26 are deceased, including A. Hair, H. Newton, Ellis and George Buckner, A. Moran, L. Roberts, Hezekiah Baker and, most recently, Johnny Daniels. The full list of 26 can be found in the Florida Artists Hall of Fame, as well as various highwaymen and Florida art websites. After the Second World War, some artists took a global approach, working and exhibiting abroad, in Paris, and as the decade wore on, relocated gradually in other welcoming cities such as Copenhagen, Amsterdam, and Stockholm: Barbara Chase-Riboud, Edward Clark, Harvey Cropper, Beauford Delaney, Herbert Gentry, Bill Hutson, Clifford
