In Brecht’s poster the phrase “No Smoking” written in black simply stands out in the white space. In Maciunas’ poster, however, the typographical characters tran- sfuse and interpenetrate between black and white: they always seem on the verge of communicating something which then disappears, to simulate the evanescence of smoke like that of language and communication. Maciunas, allergic to smoke, posted it wherever he lived or worked. This poster was included in “Fluxpack 3”, published by Maciunas in 1973 and distributed by Gino Di Maggio (Milan, 1975).
