    Description

    TLS in untranslated French on Coanda letterhead from 1961 signed in blue ink by Henri Coanda.
    (1886-1972) Henri Marie Coanda was a Romanian inventor, aerodynamics pioneer, and builder of an experimental aircraft, the Coanda in 1910 described by Coanda in the mid-1950s as the world's first jet, a controversial claim disputed by some and supported by others. He invented a great number of devices, designed a "flying saucer" and discovered the Coanda effect of fluid dynamics.
    Comes with a full Letter of Authenticity from Todd Mueller Authentics if the item sells for and over.
