Knight Terrors: Detective Comics #2 p.26

Mike Perkins was tapped to fill-in for Riccardo Federici on 7 pages in this issue, from page 23 to page 29 inclusive, and since Federici's pages were being published in pencil form only, Perkins decided to not only do the same, but even emulated Federici's style to some degree in order to keep the look of the art consistent throughout the issue. Beautiful stuff!
