I decided to draw a guy playing a saxophone because when I think of 1920s I think of the saxophone. The sax is also cool lookin, and I want to learn it but that's a lot of time and effort, and the 1920s are known for the music, and The rise of the saxophone as a jazz instrument followed its widespread adoption in dance bands during the early 1920s. And the 1920s is a time of change and growth for the U.S. What exactly changed in the 1920s was a decade of profound social changes. The most obvious signs of change were the rise of a consumer-oriented economy and of mass entertainment, which helped to bring about a "revolution in morals and manners." Sexual mores, gender roles, hair styles, and dress all changed profoundly during the 1920s
