Vintage first day cover honoring Harry S. Truman signed in blue ballpoint ink by Chester Bowles. Dated in 1976. In very good condition. Chester Bliss Bowles (April 5, 1901 – May 25, 1986) was an American diplomat and ambassador, governor of Connecticut, congressman and co-founder of a major advertising agency, Benton & Bowles, now part of Publicis Groupe. Bowles is best known for his influence on American foreign policy during Cold War years, when he argued that economic assistance to the Third World was the best means to fight communism, and even more important, to create a more peaceable world order. During World War II, he held high office in Washington as director of the Office of Price Administration, and control of setting consumer prices. Just after the war, he was the chief of the Office of Economic Stabilization, but had great difficulty controlling inflation. Moving into state politics, he served a term as governor of Connecticut from 1949 to 1951.
