Judge Dredd #13
"French for Black"
An experimental retro-virus is released on a sector of MC-1, devolving the area a full century and a half! When Judge Dredd steps in to investigate, he's caught up in the wave, too, which means goodbye helmet and Lawgiver -- and hello Fedora and gat. This is Dredd like you've never seen him before. This is Dredd... noir-style!
