July is going to be an expensive month.
“When Image Comics publish The Walking Dead #100 in July, they’ll be doing so with a bang. As well as Charlie Adlard doing a cover, a wraparound cover and seeing his work transformed into a Chromium cover, there will also be covers by fellow Image stable mates Frank Quitely, Todd McFarlane, Marc Silvestri, Bryan Hitch, Sean Phillips and Ryan Ottley.
The comic is the fifth Image title to reach such lofty heights, after Spawn, Savage Dragon, Witchblade and The Darkness, and the only title not created by one of the original founders.”

If each one of them do a cover we're looking at at least 8 (if Adlard's first STF promo is only in Chromium) Let's hope some of those are relegated to SDCC and not 1:250 variants.
