The cover of The Sandman: The Sound of Her Wings (vol. 1/#8), by Dave McKean
Looks like watercolour on paper, 1991
The Sandman is one of the graphic novels (an ongoing series, in fact!) that has helped to define the genre. I've never read it (I'm not much for Neil Gaiman--begin gasps and rage), but I know that it has been vastly influential and one of the reasons why Vertigo became such a juggernaut in the comics industry. The Sandman has won dozens of Eisner Awards, which is like the Oscars for graphic novels and comics.
