Fax from Sarajevo by Kubert is a must, and I'd probably say Contract with God(and its sequels) would get the number two spot...but I'm torn on the third. I'd say either Enemy Ace: War Idyll by George Pratt, Tintin: The Crab with the Golden Claws by Herge, The Last Temptation by Gaiman and Alice Cooper and The Midnight Circus by Mike Mignola are all tied for that last spot.
Wow. I've read exactly one of these.
I'm going to guess Contract with God( I haven't made it over to your Eisner thread so maybe you haven't gotten there yet.)
A life is like a garden. Perfect moments can be had, but not preserved, except in memory. LLAP
