He wasn't young -- 95? Few people ever get there -- and I wasn't a huge fan of comicbooks* and yet-- It's surprisingly saddening. The guy who wrote those funny/snarky things in the back of the better comics and signed off with "Excelsior," gone? The fellow who put in a cameo in movies featuring characters from magazines he edited, always there in the background, no more?
It's painful. I'm going to miss him. A little of my childhood goes with him. A little of a lot of people's childhoods goes with him.
* His preferred version of the word, according to some sources.
