José Antonio Muñoz or simply Muñoz (born July 10, 1942) is an Argentine artist. He is most notable for his influential black-and-white artwork. His hardboiled graphic novels series Alack Sinner (with writer Carlos Sampayo) is a noted source for Frank Miller's Sin City.
Muñoz was born in Buenos Aires. He studied at the Escuela Panamericana de Arte under Hugo Pratt and Alberto Breccia, and worked as an assistant to Francisco Solano López.
In 1972 he moved to Spain and then to Italy and began a collaboration with Argentine writer Carlos Sampayo which produced, among others, the detective series Alack Sinner (sometimes misspelled "Allack Sinner") and its spin-offs Joe's Bar and Sophie, as well as a comics biography of Billie Holiday.
His style is characterised by a sharp line, heavy chiaroscuro, and exaggerated, sometimes grotesque, faces and figures. His work has had a strong influence on Argentine Alberto Breccia, his teacher. Also British artists Dave McKean and Warren Pleece, and US artists Frank Miller (for part of his Sin City style ) and Keith Giffen.
