I remember being very disappointed when I discovered that this drawing was a standalone piece, and not a panel from a complete Batman story illustrated by Moebius.
Jean Giraud, AKA Moebius sadly died on March 10th.
Obituary for artist Jean Giraud, in The Guardian:
Giraud… had an impact on the visual arts that went beyond comics. He was seen as a figurehead linking bandes dessinées with modernism and nouveau réalisme. As the co-creator of Métal Hurlant magazine, he took comics to an older, more literate audience. In cinema, his fans ranged from Federico Fellini to Hayao Miyazaki and his style influenced dozens of others, including Ridley Scott, George Lucas, James Cameron and Luc Besson.
Tom Spurgeon also has an in-depth obituary at The Comics Reporter:
Giraud would… describe the revolution driven by his work and others as one of creative choice rather than content, that the feeling of the artist inhabiting the work was more important than the kind of work being done. He drew a connection to the undergrounds and cartoonists like Robert Crumb, although he felt that the work of he and his peers existed in an entirely different cultural context.
