Symbols of power and progress

the long version

"Beginning with the early 1930s, advertising designers developed trademarks into powerful symbols reflecting not only their client's products but, collectively, the economic recovery from the Great Depression. Certain visual symbols, concepts and attitudes identify the design work of the period. The lightning bolt was one of the principal visual symbols. Streamlining and Bauhaus permeated their style, and a tendency toward the romantic and heroic was noticeable in their visual imagery. This book includes many excellent selections of trademarks from this eventful period."--book jacket.
