Have you seen the List of Sam & Max stories
page at the wiki yet? The bulk of that info is taken from the old comicography and this thread. Let me know if there's anything missing or wrong with it and I'll fix it up.
I'm keeping this thread in mind in case we need any covers, but I think we're good for the moment. I'll think about what to do with the non-Sam & Max comics by Steve Purcell. Some of that stuff could go on the Steve Purcell page if nothing else.
