From an article about an exhibition by GIUSEPPE CORDONI

Human beings of different ages: old men with long beard, emaciated girls, hard-profiled men or frightened children, all these appear on a canvas after another: human beings swarming, aggressed upon and crushed by their sadness, just like glass is crushed by lead. And in every painting, the background chromatic notes stress this expressionism which exasperates the precarious images, turning predominant feeling into: ill grey-blue like the painting "Rainy Day" (Giornata di Pioggia); loud pink-yellow like "Friends at the Inn" (Amici all’Osteria), or mallow-green, where the faces lay still, just like imprisoned frogs in a dead marsh, - "In the Country" (In Campagna).
So, painting after painting, this absurd portrait of human suffering gets bigger and bigger. And Flavio never seems to surrender, never seems to remove the paintbrush from the canvas, just like a long time ago he would never remove his penknife from the black school-desk.
He insists on searching,, among his huge number of images, the root, the seedling, the trail of a smile, a smile which seems to have disappeared for ever.

Have written about him also: Krimer, Moscatelli, Cagetti, Paloscia, Falossi e Cennamo.
