In the 20th century, in 1931, the artist Iakov Guminer supported Stalin's shortened production schedule for the economy of the Soviet Union with a propaganda poster that announced the "Arithmetic of an Alternative Plan: 2 + 2 plus the Enthusiasm of the Workers = 5", which exhorted Soviet workers' to realise five years of economic production in four years' time—consequent to Stalin's announcement, in 1930, that the first five-year plan (1928–1933) instead would be completed in 1932, in four years' time.
