On Twitter, artist J. Scott Campbell revealed the finished version of his bagged variant cover for "Harley's Little Black Book" #1 and offered a few glimpses into his creative process behind it.

The bi-monthly series is written by the "Harley Quinn" team of Jimmy Palmiotti and Amanda Conner. Conner -- and "a bunch of people who owe her favors" -- will handle art for the series described by DC as "overstuffed" and "oversized." Each issue will find Harley teaming with one of the DCU's biggest heroes or villains, with Wonder Woman helping to kick the series off.

"Harley's Little Black Book" #1 arrives at retailers on December 2.
