My good friend told me that pince-nez was very popular in the former Soviet Union. He wasn't kidding. I ran across a picture of Vyacheslav Molotov, the Soviet diplomat under Stalin's reign. He signed the non-aggression pact with the Nazis in 1939 and later had a "cocktail" named after him.
Like Trotsky, Molotov wore the fingerpiece style. A sharp look! I especially like this side view of Molotov as it highlights his pince-nez.
According to Wikipedia, Molotov died in 1986 at the ripe old age of ninety-six. That was quite an accomplishment for someone who served under Stalin.
