Early in the 1980s, during the period of martial law, an outstanding generation of Polish artists started to make its mark a generation which now, in its late 30s and early 40s, is producing mature, exciting work: video art, sculptures and installations as well as paintings.
The incident bore similarities with the daubing of a Mark Rothko mural in London's Tate Modern gallery last October, for which Polish national Wlodzimierz Umaniec, 26, was subsequently jailed.
