Jean Dubuffet (1901-1985)

"Within these graphisms, imprecise, fugitive and ambiguous figures take shape. Their movement sets off in the observer's mind a hyperactivation of the visionary faculty. In these interlacings all kinds of objects form and dissolve as the eyes scan the surface, linking intimately the transitory and the permanent, the real and the fallacious" (J. Dubuffet, 'Remarks on the Unveiling of The Group of Four Trees', New York, 24 October 1972, reprinted in Jean Dubuffet: A Retrospective,  Solomon R. Guggenheim Museum, New York, 1973, p.35).
