What are some of your favorite graphic novels?

I have many, but I’ll list the ones I like the most. I’d like to hear what others like.
Sandman—the whole series
Watchmen
V for Vendetta
Sin City
The Tick
Fax From Sarajevo
Batman, the Dark Knight Returns
300
Ghost World
From Hell
Books of Magic (the early ones—it got bad toward the end)

…and the list goes on. But those are probably my favorite—at least those that I can remember off the top of my head.
