In case you’re into both comic books and music, there’s a good conversation from this past February on the Comics Journal message board, dealing with album art done by comics artists. The thread is rife with the requisite message board fodder – broken image links and multiple postings from people struggling with image tags – but there’s enough there to make it worth visiting.
There were several covers that I never would have recognized by artists I’m familiar with, as well as some that I’m just so used to seeing that the familiarity of the artwork never occurred to me. It also yields links to two sites that cover the same material more thoroughly (Though both are text-based so you don’t get to see the images).
