Howard Hallis has been drawing pop culture icons, historical figures, and just about anything he can think of since 1997. He's hasn't stopped drawing since that year because what he's working on is The Picture of Everything.

Over the years, Hallis has been making this picture in sections, and in some of these selections you can sorta see parts where those sections appear to have been combined (though it could be just a fold in the paper):

You can find the whole picture on Hallis' site, complete with a key to who's who and what's what, but I warn you: Odds are that you'll be like me and have your mind blown by the sheer size of this "work in progress." [The Picture of Everything]
