The coin's reverse shows an image of Konstanty Ildefons Gałczyński. On the left side there is an image of a green goose. On the obverse there is an image of a carriage and horses.  Konstanty Ildefons Gałczyński was born on 23 January 1905 in Warsaw. He announced his first work in 1923, but his debut is considered to be his poetic novel "Porfirion Osiełek" published six years later. Gałczyński studied English and classical philology at the University of Warsaw. In the 1939 campaign, Gałczyński took part as a soldier of the Border Protection Corps on the eastern border. On 17 September he was taken prisoner by the Soviets and sent to the camp in Kozelsk. It is from this period that the poems "Song of the Soldiers from Westerplatte" and "Soldier's Dream" come from. In October 1939, together with other privates, he was exchanged for Soviet citizens who remained on the German side of the Bug River. The poet was sent to the German transit camp in Muehlberg. After being liberated by British troops, the poet was sent to the transition camp in Hoexter, in Wesfalia. In a transport of women prisoners from Ravensbruck, Gałczyński met his Lviv friend Lucyna Wolanowska. In January 1946, the poet's son, also Konstanty Ildefons Gałczyński, was born out of this union. In March 1946, Gałczyński returned to Poland and settled with his family in Kraków. The poet began working with "Przekroj", renewed contact with "Szpilki", and also published in "Tygodnik Powszechny" and in "Odrodzenie" in Warsaw. In "Przekroj", "Listy z fiołkiem" and literary miniatures "Zielona gęś" were published. In June 1950, at the congress of writers, Adam Ważyk, in his programmatic paper, subjected the work of Gałczyński to devastating criticism. Green Goose and Letters with a Violet disappeared from Przekrój and the poet's work was banned from printing. Gałczyński fell seriously ill, had a heart attack in March 1952 and was depressed. On December 6, 1953, he had a second heart attack which he did not survive.
