Photographs of Promethean leaders were purchased by the Józef Piłsudski Institute in London from Mychailo Jeremijew, Ukrainian journalist, politician, and Promethean acitivist in 1969. They include the rare images of historical figures such as Symon Petliura, head of the Ukrainian People's Republic, Kekutsa Cholokashvili, leader of anti-Soviet guerilla units in Georgia, and Tadeusz Hołówko, Polish politician and victim of the Organization of Ukrainian Nationalists. Both Petliura and Cholokashvili are considered national heroes of Ukrainian and Georgian independence movements. Other photographs include Kalmuk, Azeri, Armenian, Turkmen, Kozak, and Ukrainian leaders and exiles who participated in the Promethean movement.
