Accompanied by a letter of authenticity, in Russian, from the original recipient of the tube, which reads, “This tube ‘Black Current Juice’ was on board the spaceship controlled by Gagarin and was given to me by Gagarin as a present with a dedication after the flight. The sheet with the dedication was lost in the meantime.” In fine condition, with expected wear from use. A great relic from the first human space flight. RRAuction COA.
