He graduated from the Faculty of Graphic Arts at Vilnius Art Academy in 1950, and from then on an artist Birutė Žilytė was his partner in life and creation until the very end of his life.

Steponavičius illustrated books by Kazys Boruta, Vincas Krėvė, Kostas Kubilinskas, and the illustrations for the latter’s book “Varlė karalienė” [Queen Frog] were awarded the gold medal in an international book exhibition in Leipzig. Whereas the illustrations for Cvirka’s book “Nemuno šalies pasakos” [the Tales of Nemunas country] needed almost ten years to complete, and the author received a national prize for it in 1990.
