Leaflet from the 1920 Polish-Soviet war with a poem by J. Kasprowicz

SONG of a volunteer. It is not for nothing that today I am called out / This Polish country of mine / "What you have the best in you / To me, brother, give". [...]. This song was composed by the poet, who came into the world in a peasant hut, for those who go to defend the Fatherland [...]. So choose, boys: voluntarily with your own army on the enemy, or under compulsion with the Muscovite and the Chinese on your own brothers [...]. [Kraków? 1920].
