I have two more graphic novels to recommend (it's a long drive from lethbridge to edmonton). Both are by Craig Thompson: Blankets and Carnet de Voyage. Blankets is about his first love, reminds me a little of Unlikely and Clumsy, only not as sad (see November 9 and 27 posts). Carnet de Voyage is a sort of travel journal of his time in France, Spain and Northern Africa.
You can view his art and see panels from his books on his site.
