Nannucci, Maurizio. Another Notion of Possibility. Black billiard ball with engraved lettering in original black slipcase with blind-stamped cover title. Signed and numbered and with a dedication by the artist in his own hand on the enclosed edition folding card. Copy: 10/50. Toronto, Shark Editions, 1998. Diameter of the sphere: 5.7 cm. Dimensions of the box: 9 x 9 x 9 cm. First "billiard ball" by Maurizio Nannucci (born 1939), probably the most important representative of conceptual art in Italy, whose neon installation "Blue Ring" illuminates the library of the German Bundestag with Hannah Arendt's words "Freedom is conceivable as a possibility of action among equals / Equality is conceivable as a possibility of action for freedom". - The box minimally rubbed, otherwise very good.
