This image dates from 1941 and was created in protest of the Hays Production Code. It featured ten of the hot button items that films of the day had to avoid. Amusingly, smoking wasn’t one of them, so that dangling cigarette in her lips was just an artistic touch. A glimpse of lacy lingerie on an exposed thigh was apparently much more dangerous.
According to Wikipedia the code ultimately expanded to around 25 different problem areas, which would be tough to fit into a single photographic still. However, looking back at the list now, any random episode of Narco’s probably covers a significant fraction of them.
This image was created by A. L. “Whitey” Schafer. You can read more about him here. I found it via this tweet.
