Best known for his iconic Woolmark logo, Franco Grignani (1908-1999) was an influential artist and graphic designer whose dazzling works anticipated Op Art.0Briefly affiliated with the Futurist movement as a young painter, he subsequently adopted a geometric abstract style that revealed an increasing fascination with optical effects and perceptual processes. From the late 1940s onward, Grignani's works took inspiration from Gestalt Psychology, and were characterized by their use of dynamic forms and 'virtual' shapes that seem to warp out of, and recede back into, the surfaces of his compositions.0Initially, Grignani's experimental approach was not understood by the artistic establishment of the day, and he worked largely in isolation. Yet he achieved great success as a graphic designer, creating striking advertising campaigns for a variety of high-profile companies including Pirelli, Fiat and Alfieri & Lacroix, as well as producing covers for a series of science fiction novels published by Penguin during the late 1960s.00Exhibition: Estorick Collection of Modern Italian Art, London, UK (05.07.-10.09.2017).
