This is Klaus Janson as inker. But don't you dare call him a "tracer". He added levels of realism and dimensions to John Romita Jr's pencils. Even the Joker and Jigsaw peed in their pants at the sight of Bats and Punny duking it out.
Recommended Klaus Janson Batwerks: "Gothic" (Grant Morrison only supplied the words) and "Death And The Maidens" (Greg Rucka wrote some words to go along with Janson's art).
