There was an article written in 1942 about writing for comic books. This article was reprinted in a modern comic magazine, which I read within the last several months. At the end of the article, there was a list of addresses for all the major publishers of that time period, some of which had an editor listed, as well.
Unfortunately, I didn't take note of what magazine the article appeared in. I can only guess that, when I read the article, I figured I would go back to it within a few days to record the information I wanted to get out of it. I didn't get back to it soon enough, getting sidetracked with various things, and now I can't remember which magazine the article appeared in (I read a lot), so I'm hoping someone knows what I'm talking about and can point me in the right direction.
