The Czech stamp depicts two mythical figures of Czech history, Libuše and Přemysl. Libuše, one of the three daughters of the Czech ruler Krok, was a legendary Czech princess and wife of Přemysl the Ploughman. She became famous as a prophetess who foretold the glory of the city of Prague, founded by her. Princess Libuše married Přemysl the Ploughman and together established the oldest Czech ruling dynasty of the Přemyslids.
