Honorable mentions:
>Amazing Spider-Man #121-122 (Gerry Conway and Gil Kane)
>Wrinkles (Paco Roca)
>A Small Killing (Alan Moore and Oscar Zarate)
>Duck Avenger New Adventures (Alessandro Sisti, Ezio Sisto, Claudio Sciarrone, Max Monteduro)
>The Incal (Alejandro Jodorowsky and Mœbius)

I would also include Rowlf by Richard Corben, but it's been a very recent read of mine, so I don't want to be influenced by recency bias.
