Saw a couple of others like this here(Luigi), anyone know who made them and where there from? Bad ass; Ultimate Nintendo presents Ultimate Mario Brothers, from the creators or Ultimate Hyrule Fantasies: The Legend of Zelda ;-)
source added, the artist is Jose "Emroca" Flores. there's a slightly reworked, higher-res version at his blog, where you can also buy a print of it! http://emroca.blogspot.com/
