Acclaimed illustrator Yuko Shimizu, perhaps best known to comics readers for her Eisner-nominated work on Vertigo's The Unwritten, is branching out into the DC Universe with a cover for an upcoming issue of Detective Comics. And for the past few weeks, she's been offering her Facebook followers a glimpse into the cover process, from reference material and initial sketch to inking details and finally, last night, a taste of colors. Alas, that may be all we see until DC releases the solicitations for that issue.

"Alright, this may be the last share," Shimizu writes. "For the final result, please see it on an upcoming cover of DC Universe's Detective Comics. My editor is on vacation, so I am not certain which month this is going to be."

See some of Shimizu's process below, and more on her Facebook page.
