Identical postage stamps, depicting Mirosław Hermaszewski were also printed. Both versions were made ahead of the start of Soyuz 30 mission, as it was not decided yet, who would be chosen for the mission. Following Hermaszewski being chosen for the mission, the stamps of Jankowki were ordered to be destroyed.
