The doodle was drawn up by Andrea Garofalo, Mario Wario, Antonio Turchiarelli and Adelmo Monachese to mark the anniversary of the death of Borsellino, who was killed by a mafia car bomb in Palermo in 1992, less than two months after fellow magistrate and friend Falcone was assassinated.
The teenagers said the example they set in fighting the mafia "must never be forgotten", according to a report in the Foggia edition of Corriere del Mezzogiorno.
They added that "some battles are fought on multiple fronts", and referred to the Palermo footballer Fabrizio Miccoli, who recently called Falcone "filth" in a bugged telephone conversation with a mafia boss. Miccoli, who is allegedly linked to the mafia, apologized during a tearful interview last week, although his honorary citizenship has been revoked by the town of Corleone.
Borsellino and Falcone are remembered as heroes of the fight against the mafia.
Falcone was chief prosecutor at the 1987 "maxi trial", when nearly 400 Mafia members were sent to jail. The friends met at Palermo University.
The teenagers have presented their logo to Google and are drumming up support from the public to get it published on the search engine's homepage. To support the initiative, you can send an email to firstname.lastname@example.org, attaching the logo (the image can be downloaded at www.ofalo.it).
When Google first started publishing doodles on its homepage, they mainly celebrated familiar holidays, but now highlight a wide range of events and anniversaries.
