Painter. Worked in the genres of still life, landscape, theatrical portraits and nu. At the MSPSA (1901-1905, 1907-1909) his teachers were K.A.Korovin and V.A.Serov. He developed his own painting style from the mid 1900s, particularly following a trip to Europe (1908). I.I. Mashkov was one of the leading members of the Jack of Diamonds society. His creative work reflected the colour revolution of the 20th century. The artistic innovations of P. Cezanne and H. Matisse were evident in his paintings which contained the full-blooded energy of folk art. Turbulent colour expression, infected with vital energy, is combined with the laws of primary symmetry characteristic of urban folklore: signs, trays. The artist achieved particular expressiveness in still life, his favourite genre. He hyperboles the material world, condenses forms, dramatises colour contrasts and exaggerates texture, creating powerful pictorial formulas. In addition to the Jack of Diamonds main genre of still life (Still Life. Fruit in a Dish, 1910; The Pumpkin 1914), Mashkov created theatrical, shocking portraits ("Portrait of I.E.Kirkcaldy", 1910; "Self-Portrait", 1911). In the 1920-1930s the artist tried to amalgamate his innnovative achievements with the refinement of paintings by old masters ("Food, Moscow Bread", 1924). Later the artist followed the principles of Socialist Realism. Remaining true to his great love for nature, he continued to produce masterpieces ("Still Life. Pineapples and Bananas", 1938).
