CRISIS ON INFINITE EARTHS #10 (Jan 1986)

From http://www.theartistschoice.com/vey.htm :

All Art by Al Vey based on original linework by George Perez

Due to not having quality images of the Monitor Tapes feature of Crisis Issue 10, DC hired Mr. Vey to redo those parts to be part of future releases of COIE in various formats.  Mr. Vey was given a B&W copy of these pages for reference and redid all the Monitor Tape Subset of panels on a total of 7 boards (Shown Below). These pages were not physically worked on by Mr. Perez in any way. They are the artwork used for publication of the story for the Hardcover and subsequent Trade Paperback Editions.  These Pages are sold only as a set and are Make an Offer Only.  Each page also contains an overlay with the wording and any appropriate logos."
