Born in a family of day labourers often forced to move, Pietro Ghizzardi, a frail child, suffered from these continual changes which prevented him from fregular schooling. In 1931, his family finally moved to Boretto. The great flood of the Po River in 1951 seemed to be a turning point: it is from this period that Pietro Ghizzardi devoted himself only to painting and writing his autobiography. Created on recovered cardboard with herbs, wine, blood, mulberry juice, soot, magazine clippings, his drawings feature his parents, saints, wild animals, entertainers and plump women. His work would become gradually more dull under the pressure of his family, which only perceived it as an obscenity.
