Final answer:
The American version of Art Deco known for its local stylistic inspirations in the 1920s is called Art Moderne or the Streamline Moderne. It is characterized by aerodynamic shapes, long horizontal lines, and reduced ornamentation compared to the traditional Art Deco style.
Step-by-step explanation:
The American version of Art Deco that spread in the 1920s, reflecting local stylistic inspirations, became known as Art Moderne, also popularly referred to as the Streamline Moderne. This was a style that emerged during the 1930s, evolving from the Art Deco movement. Streamline Moderne was characterized by its emphasis on curving forms, long horizontal lines, and often nautical elements, representing luxury, glamor, exuberance, and the era's faith in social and technological progress. While Art Deco combined traditional craft motifs with the Machine Age imagery and materials, epitomized by bold geometric forms and rich colors, Streamline Moderne stripped away much of Art Deco's ornamentation in favor of more aerodynamic, pure-line concepts of motion and speed, responding both to the aesthetic movement and the austere economic times. Significant examples of Art Deco and Streamline Moderne architecture can be found across the urban United States, particularly in cities like New York, Chicago, Detroit, California, and Miami.
