Possibly used by Armstrong while in his Naval training circa 1949-1950. We feel that much of what he learned here served him well in later years, especially Book Seven. Generally fine. This lot will include encapsulated CAG Photo Certificates with a Statement of Provenance signed by Neil Armstrong's sons, Rick and Mark.
