David Klein (February 13, 1918 - December 9, 2005) was a commercial artist best known for a series of travel posters depicting various cities and countries around the world that he produced for Trans World Airlines. Born in El Paso, Texas, Klein moved with his family to Los Angeles as a youth and later attended the Art Center School (now the ArtCenter College of Design) there. He began to make a name for himself as a watercolorist in California, but the Second World War intervened and Klein spent the war illustrating Army manuals, with his work being so well regarded that it was used to help form the Air Force Art Program in the postwar period. After the war, Klein moved to Brooklyn, New York, where he would spend the rest of his life. He became an established illustrator for Broadway show posters and in the 1950s and 1960s produced the aforementioned travel posters for TWA, which are considered emblematic of the 'Jet Set Style' of artistic and cultural production. Klein continued to produce commercial art for various clients for many years afterwards, but also returned to producing non-commercial artistic works late in life.
