The Jury of the Nonino Risit d’Aur Prize […] has wanted to remember Gianni Bosio’s research, the author of the monograph “Il trattore ad acqua negra”, published in September 1981 by the editor De Donato. The work, started at the end of the Fifties and remained unfinished because of the writer’s death in August 1971, was remembered and signaled with a particular mention as one of the several witnesses of the civil commitment and cultural work of Gianni Bosio, an important protagonist of the rural history of our Country.
