Mother's Day Pick Von Braun, Wernher. (1912–1977) Typed Letter Signed Certified [ba57glmS]

TLS from the famous aerospace engineer to Professor Irma Antonetto of the Associazione Culturale Italiana, responding to an invitation to speak.  June 16, 1972;  1 pp., on A4 National Aeronautics and Space Administration stationary.  In part, "Since I have recently resigned from the National Aeronautics and Space Administration to accept a position in the aerospace industry, I am unable to assume any additional commitments at the present time."  Two holes to left margin, else fine.
