DeWitt Clinton High School History of the World mural by Alfred Floegel, WPA Federal Art Project, 1934-40.

Sign that was posted for some years with the murals (dating from after area code 718 was created in 1984). The principal had it in his office. I should have asked him why it wasn't posted with the mural any more. Orders from on high? It was probably the only sign in all of New York City that gave credit to the WPA for anything.
