about Arzach i think you can get some spanish editions, as it's a comic without text, maybe you find some in todocoleccion.net kind of ebay, it works good, and is available english lenguage.
(gimme a hit if you need links)
One of the latest series i read was Miracleman by Alan Moore and various (John Tottlebem, Alan Davis, Rick Veich) i didn't have the oportunity to read it on paper until a few weeks when a friedn borrewed me the 11 numbers (i don't like to much read scans). And i have to say i liked a lot, is really realistc from begining to end. The only bad thing it has this series is that beatdowns a lot of moderm superhero comics like The Authority, or even Sleeper. A must read for me. Probably Marvel will finally reprint the Alan Moore's run soon.
And then i have to recomend you this masterpiece of art wich is called
Takemitsu Samurai by Iseei Eifuku and Taiyo Matsumoto (Tekkon Kinkret), i read the two first volumes published in spain by glenat.
The story follows Soichiro, a samurai wich sells his sword, his soul.
The artwork is just mindblowing, if you like samurai comics or simply a nice story check it out. sorry if there is no english edition.
Anyone read those?
Wish you like!
