The Grabowski Gallery was an avant-garde art gallery opened in 1959 in London's Chelsea by Mateusz Grabowski, anticipating the Swinging Sixties. It hosted some of the earliest shows of the rising pop art movement and was the first venue in London to bring op art to the public. It launched the careers of some of Britain's and the British Commonwealth's leading exponents of two- and three-dimensional art and fostered émigré artists from Europe, the Caribbean and the Commonwealth. By the time it closed its doors in 1975 it had mounted around two hundred shows. When the gallery closed Mateusz Grabowski donated his collection of works from the gallery to the Museum of Art in Łódź and the National Museum in Warsaw, Poland.
