It's a very interesting form of art, and unfortunately I didn't have much access to it until I moved to the US in 2003.
I am currently reading "Palestine" by Joe Sacco, and "Watchmen" by Alan Moore and Dave Gibbons.
In the meantime, I just got this very cool link where you can see comic book covers.
Enjoy it, and if you have any good recommendations for graphic novels, I would love to read them.
