I was experimenting with the bookmark layout I use for Bookmark Dungeons and seeing if I could fit a beastie on there. This is the result. This would work well for most monsters, though I think many of the more interesting ones would get a bit crowded or not fit at all.

Al Williamson's portrayal of the sword & planet genre, mostly through his work on Flash Gordon has long been my favorite. While Frazetta rightfully gets credit for his fantastic interpretations of the works of Edgar Rice Burroughs, Williamson is the artist I would mostly liked to have seen do adaptations of the John Carter of Mars books into graphic format. Particularly his portrayal of fantastic cities on alien worlds.
Recently Flesk Publishing put together an amazing retrospective of Al Williamson's work that I highly recommend for any fan of pulp science fiction and adventure.
