Flown cover carried on Soyuz MS-10 and Soyuz MS-12, signed in ink by Oleg Kononenko, David Saint-Jacques, Anne McClain, Aleksey Ovchinin, Nick Hague, Christina Koch, Aleksandr Skvortsov, Luca Parmitano, Andrew Morgan, Oleg Skripochka, Jessica Meir, and Hazza Al Mansouri. During the failed Soyuz MS-10 flight, this cover was held inside the orbital module which crashed to Earth from the height of 50 kilometers without a parachute—hence the wrinkles in the corners. In very good condition, with overall somewhat heavy creasing. Accompanied by a certificate of authenticity from Walter Michael Hopferwiser. A desirable piece of flown 'crash mail,' signed by a dozen members of ISS expeditions.
