Leonov and Kubasov Autographs

Leonov and Kubasov Autographs on a presentation certificate that accompanies the book "Soyuz-Apollo" (75pp., hard, in Russian). An award certificate on the first page reads "To major-engineer Marchenko E.I. for active participation in preparing and carrying out of the first international experimental space flight program 'Soyuz-Apollo'". The citation is signed by cosmonaut Beregovay (as head of the Center of Cosmonaut Training) and general-major of the Air Force Vaganov (as the head of the political department of the center). The citation was issued in Star City in July 1975. The book is also autographed on page 27 by the heads of the 3rd and 4th Russian back-up crews, Dzhanibekov and Romanenko. Very good condition with modest cover faults.
