Signed by hand by Bruce Timm, Amanda Conner and Jimmy Palmiotti and signed and sketched by Paul Dini, this blank frame variant cover to Harley Quinn &Her Gang of Harleys #1 is professionally graded by CGC and is part of their special Signature Series. With Signature Series books, a certified witness actually observes the signing/sketch of the book and then immediately takes possession of the comic so there is no chance for the real autograph/sketch being replaced or substituted. CGC case is scratch and defect free and will be shipped with the utmost care.
