Moscow, 4 August, 1945. The European chapter of World War Two was over, and the US and the USSR were pondering their future relationship.

They presented a large, hand-carved ceremonial seal of the United States of America to Averell Harriman, the US ambassador. It was later to become known simply as The Thing.
