I picked up all four of the latest "Disney Treasures" deeveedees today, and sampled a bit of all four of them.
Very tasty dishes, indeed.
My early favorite is the Tomorrow Land set, with its' mid-fifties "science faction" documentaries, even though seeing Werner von Braun raised my blood pressure a bit. The animation in these shows, which were essentially promotional films for the US space program, is very distinctively "fifties" in style, and quite unlike anything Disney has made before or since.
