Comic book artist Jim Mooney, a veteran of the Golden Age and the Silver Age of comics, has passed away. He had been in failing health for a while.
He began working in 1940, the year after Superman's debut. After freelancing for Fox, Fiction House, Timely, the Eisner-Iger Studio, he settled in at DC Comics, where he drew pretty much all of their top-selling titles. Perhaps best known for his run on the Supergirl comic (1959-68), he was a DC regular from 1946 to 1968. In the 1970s and 80s, he worked for Marvel.
