In El Diablo, Erró brings together imagery drawn from comic books and popular culture in a vivid, densely layered composition. Against a striking yellow background, figures from Western comics collide with mechanical structures and stylized human forms, creating a scene filled with tension, movement, and visual contrasts.

Part of the artist's La Grande Parade series, the painting reflects Erró's distinctive approach to visual collage, combining familiar imagery from different sources into an unexpected and theatrical narrative.
