Subsequently Toppi worked mainly for one-shot titles, with the exception of the eccentric Collezionista ("Collector") of 1984. He produced adventure/historical titles for CEPIM's Un uomo un'avventura and, for the French publisher Larrousse, some episodes of Histoire de France en bandes dessinées and La Découverte du Monde.
Toppi's works appeared on a host of titles in Italy and abroad: an incomplete list could include Linus, Corto Maltese, Sgt. Kirk and Il Giornalino in Italy. His strips were collected in several books. He last worked with the French publisher Mosquito, with which he made 22 books since 1994.
