Just watched the feature film “The Flapper” (1920) last night, starring Olive Thomas. Probably not what most people would envision, as most nowadays would associate the term flapper to the wilder days of the late-1920s. This conveyed a much different world. Seems to be quite a big cultural gap between 1920 and 1929.
As for the 1930s, it’s always interested me that as the politics went far left, the culture retrenched and became a bit more conservative. Maybe it was just due to the economic hard times, or a sort of recognition that things had gone too far in the 1920s, and an instinctive inclination that folks were now paying for it. Add a certain nostalgia for the pre-WW1 era, which always tended to strike a lot of people as the demarcation point for when history started going nuts.
Hadn’t seen that movie. I’ll look for it. One of my favorites, though a bit silly, period movies of the twenties is Thoroughly Modern Milly.
