"One of the earliest post-war books on rocketry. This important work provides a compilation of the material obtained by Uytenbogaart for the Allies during World War II. Includes detailed information on V-2 design and operations (including maps of launch sites), the use of rockets for space travel, and a mathematical analysis of rocket dynamics."
Ciancone notes this edition is known in blue or black cloth with no priority known. He does not note this variation with the presentation bookplate, which we've seen with one author signature, and now for only the second time with both author signatures.
