Rare pairing of original German Raketenflug newsletters from April 1933 and August 1953, 5.75 x 9 and 5.75 x 8.25, with the 1933 newsletter signed on the front cover in black ink, "H. Oberth." In overall fine condition, with scattered creasing. A very desirable offering given that many German rocket scientists subscribed to this newsletter well before the threat of World War II. From the collection of aerospace memorabilia specialist Ken Havekotte.
