Catholic and Orthodox Christians in Ukraine will not celebrate Easter until the 1st of May, however here is a vintage Ukrainian Easter print by artist Jacques Hnizdovsky.
The writing in the print says: Христос Воскрес! (Khrystos Voskres!), with the response: Воїстину Воскрес! (Voyistynu Voskres!).
This means Christ is Risen! Truly He is Risen! The interaction is heard frequently at Easter, and for some weeks afterwards.
