In the 2019-20 season, the Certaldese football celebrated its first hundred years of life and after the official celebrations of the Valdelsan club, the publication containing this specific century of football had long been awaited. From the rossoblù of the "Giovanni Boccaccio" and from the first experiences of the pre-war championships, in 1945 we reach the viola of AS Certaldo which for several seasons was the protagonist of national categories such as the Interregional Promotion, the Interregional Championship and the National Amateur Championship . The work could not fail to contain many unpublished images that accompany the story of a century of football life with the full-bodied set of all the scores of the official championship and Italian Cup matches.
