from "I Killed Marty Feldman" in Solo #11 (DC, August 2006); script, pencils, and inks by Sergio Aragonés; letters by Stan Sakai
As you might suspect from the title of the story, Marty Feldman died the night before, December 2, of a heart attack. Sergio feared that he'd killed him by surprising him while wearing a police uniform for a movie role. (See more in this post.) Graham Chapman was with Marty when he passed away, and he would have probably mentioned it, so I think you're innocent, Sergio.
