Operation Moon is an early SRA (Science Research Associates) school reading pamphlet from the 1st year of the program in 1955. (For more about SRA read here). It covers the basics of spaceflight and then explains how we might voyage to the Moon in the future.

The "Collier's/Von Braun" rocket was still the model for the future
Similarly the Lunar Lander is also modeled after "Collier's/Von Braun"
I like very much these concrete predictions of the future.
