Sochi Olympic FDC aboard ISS.
This letter was written at Moscow’s GPO during First Day Olympic cancellation on February 7, 2014, the day when the Sochi 2014 Winter Olympic Games was officially opened. First the letter was sent by registered mail to the home address of Commander of the Russian “Soyuz TMA-12M” spacecraft. Then the letter was delivered by Soyuz TMA-12M spacecraft to the crew of the International Space Station. Aboard the station the letter was cancelled by all proper board seals on March 28, 2014, the day when Soyuz TMA-12M docked with the ISS.
