I sent you this card not by chance.

Of course, you know that it's the flag of USSR.

But do you know what this flag symbolizes?

Red color means fight for buiding communism, sickle and hammer are symbols the unity of workers and peasants, five-pointed star symbolizes the triumph of the ideas of communism on five continents.

And about the stamp.

A cracked crown means a fall of the monarchy.

In 2017 was 100 years of October revolution, so because of it were issued memorable stamps.

I hope it was interesting information for you - for a man born in the USSR.
