My uncle (retired AF) sends me a good website to check out every now and then. He forwarded this gem today. It has small movie clips that were common during WW2. They are what we would call as "commercials" when you went to the movies. My personal favorite was the "P38 Belly Tank Buggy."
Hope you enjoy them as much as I did.
