Doug: Last Friday Karen hosted a lively discussion on our favorite guest stars appearing across our comic book collections. She opened with Triton's appearances in the 1968 Sub-Mariner series, as well as Hercules frequent guest appearances in Thor's mag. You took it and ran with it, and we discussed everyone from Black Widow to the Man-Thing to Dracula! Today I'd solicit your favorite covers, and here are a few to whet your appetite. Time allowing, I will do a follow-up post with your suggestions (yes, I know I said that the last time we did this drill and then bagged it...).
