ANSA, the Italian news agency, said the drawings had once belonged to screenwriter Liliana Betti, an Adro native who worked with Fellini for more than two decades as his personal assistant, then as an assistant director for some of his films.

The exhibition is to run in the Palazzo Bargnani Dandolo until Oct. 19. It is then scheduled to move to the Filodrammatici Theatre in Milan, the news agency said.
