Comrade Popov was taking trips to various cities. From Warsaw he sent back a postcard: Greeting from Free Warsaw. From Czechoslovakia on the next trip he wrote: Greeting from Free Prague. He traveled on to Bulgaria and wrote back: Greetings from Free Sofia; and then to Hungary, writing a card back: Greetings from Free Budapest. Finally he reached Vienna and wrote his last card: Greetings from Free Popov.
