Pietro Raschitelli debuted in the late 1950s, illustrating dozens of episodes of 'Sceriffo Colt' for Editore Ardea. He produced about 20 books in the collection Albi del'Intrepido (Del Duca) over a period of three years, and then briefly moved over to Bonelli's 'Tex' series. He is also wrongly referred to as Gino Raschitelli.
