Brochure—Progress Union Pacific, From first page of brochure “Science is the fundamental keynote of Chicago’s Century of Progress Exposition of 1934. And, among the acres of floor space and ground spaces devoted to the purpose of depicting vividly how science has served the needs of man, Union Pacific’s new train is a most significant exhibit. Its ulltra-modern design and tradition-smashing type of construction is a tribute to the inventive genius of the leaders in the automotive aeronautical and railway engineering fields. Brochure in very good condition, shows all the new progress in transportation, esp Union Pacific.
