Very nice. Are these in the public domain?
As far as I'm aware they are.
Are these from the 1940's? How far into the future were they projecting?
Most are from the Forties to the early Sixties, a very few are from the late Thirties. As to the future they predicted it seems from the 1990s to maybe 2100 or beyond. Any thing to do with travel was always a favorite as it involved speed and super-highways connecting cities stretching into the sky.
Hi There!First, I love the blog! Second, I believe the image of the house at sunset/sunrise (6 from the bottom), is from the hit cartoon Kim Possible (aired on the Disney Channel from 2002-2007). It's call the Possible House.
Your observation is possibly correct. The illustration does have a sort of cartoon feel to it.
