Wilfrid Lupano spent his childhood buried in his parents' comic book collection. As a young adult, Lupano worked as a waiter to finance his studies - a combination of Philosophy and English. Together with Roland Pignault and Fred Campoy, he went on to create the humoristic western Little Big Joe. Over the following years, he penned countless titles, ranging from the four-part series Alim le Tanneur to the thriller Ma Révérence. Then, in 2014, alongside artist Paul Cauuet, he published the first volume of Old Geezers, a major hit with critics and readers alike, winning several awards including: Booksellers Comics Award, 2014; BaionaKomiki Festival, Bayonne, best album, 2014; Prix Saint-Michel, best album, 2014. Most recently, Lupano has adapted the legendary sci-fi series Valerian, collaborating with artist Mathieu Lauffray on the spin-off Shingouzlooz Inc.
