A larger question would be: Can we see the beginning of European decadence and decline in their choice of subject matter? One notices that the American artists of the same period do not limit themselves to "nekkid ladies" and seldom do they seek to shock their audience.
You might indicate that. However, at one time beginning hundreds of years earlier the artists thought there was a beauty to painting nudes. That did not go out of style. However, with these more modern day paintings of nudes in the park with fully clothed men, you might have a point.
