Alcala (1925 – 2000) was self-taught and had an established reputation as a skilled artist, and the creator of the Filipino comic book ‘Voltar’, when he began working as an inker and artist for US publications. He initially worked primarily for Marvel and DC, but starting in 1977 he worked mainly for Warren. Alcala turned to animation in 1990 and afterwards did very little comic book art.
Alcala was a superior draftsman, whose work – which had something of a 19th-century flair to it - showcased his skills at cross-hatching and shading. Despite what must have been a heavy workload for him from Marvel, Warren, and DC in the 70s and 80s, all of Alcala's stuff that saw print is of very high quality.
