I just love the detail on the Space Mountain advertisement. The rocket is going fast enough to get the kids excited, but not fast enough so that the men can’t put their arms around their wives. And space looks like the ocean.
One more ‘coming soon’ ad, this one from the inside cover of the official Disneyland 1976-1977 guidebook. What about that righteous title font? Where has all the style gone?
