From the 1920s through the 1960s, luxury travel services, including trains, generated "art photography" for pictorial magazines, advertising and publicity, and occasionally newspapers. As in this picture which was taken of a new sign Union Station at Chicago, composition was carefully posed and lighted. The picture suggests real-life, real-time activity such as that engaged in here by Elias Kummerer, who posted letters and numbers for the Broadway Limited, but worked for the Chicago Union Station Co. Raymond Loewy with Paul Cret redesigned the train in 1938, probably occasioning this new sign. The photographer is unknown, but the the backlit sign and careful illumination of Kummerer's face suggests a skilled professional at work. The Broadway LImited was an all-Pullman train; the railroad operated another train for coach passenges. See Arthur D. Dubin, "Some Classic Trains" (Kalmbach, 1964, p. 76, 91).
