Original Buckminster Fuller Signed Convocation Broadside. An original 1973 university convocation broadside featuring an original handwritten inscription and signature by R. Buckminster Fuller, one of the twentieth century’s most influential architects, inventors, futurists, and creators of the geodesic dome. The broadside advertises Fuller’s lecture. “The Prospect for Humanity”. Thursday, January 25, 1973. The piece has been personally inscribed. Followed by Buckminster Fuller’s signature in purple ink. Unlike signed books or loose signatures, this autograph appears on the original event announcement from the lecture itself, creating a wonderful association between the signature and the occasion. Best known for popularizing the geodesic dome, Fuller also introduced concepts such as the Dymaxion House, Dymaxion Car, and Spaceship Earth. His lectures attracted students, architects, scientists, and designers from around the world, and signed lecture material remains highly collectible. Original 1973 convocation broadside.
