Born on 10th July 1942, José Antonio Muñoz is an Argentine artist highly regarded for his popular black-and-white artwork. Muñoz studied at the Escuela Panamericana de Arte, where he was tutored by two industry greats - Hugo Pratt and Alberto Breccia. He became the assistant of Francisco Solano López (his work for the British Almagamated Press would be through the López studio). In the early 70s, Muñoz moved to Spain and began a fruitful collaboration with writer Carlos Sampayo. Their series Alack Sinner was published in the Italian magazine Alter Linus and the French publication, Charlie Mensuel. Other notable works followed including Le Bar à Joe and Trains sur l'Eau. These strips and many others were collected and published by such European publishers as Casterman and Futuropolis. Throughout his career he has inspired several artists, including Frank Miller and Eduardo Risso, and he has won several awards over the years, including the Grand Prix de la ville d'Angoulême at the Angoulême International Comics in 2007.
