is best known, however, for his influential work in the field of travel advertising. During the 1950s and 1960s, David Klein designed and illustrated dozens of posters for Howard Hughes’ Trans World Airlines (TWA). David’s use of bright colors depicting famous landmarks in an abstract style defined the state of poster art of the period. In 1957 a TWA poster of New York City became part of the permanent collection of the MoMA (Museum of Modern Art) in New York. These works are much imitated and to this day define the excitement and enthusiasm of the early years of post-war air travel. They defined the Jet Set style and have become iconic. David won numerous awards for Excellence from the Society of Illustrators for his TWA work, including his Philadelphia, Boston, Switzerland, and Africa poster art. David won many other awards during the 1960s for his TWA work (his Los Angeles, Rome and Paris Posters in particular) from travel, advertising, and illustration and design organizations. Klein’s work gains in popularity and his Broadway and Travel posters particularly have become sought-after collectibles Worldwide.
