...All covered in Shit...

Yeah, that's a nice song, and depicts the last part of this gallery. anyway, the artwork is great, Manekin-Eko is one of my favorite artists, but it's sad that he's not well-known yet, but with the pass of the years....

According to uploader description this set is divided into 6 parts, but I just count 5, anyway, it's really good specially the last 3 parts. Just don't come here while you're eating. Pig!

Final Call: Really worth to Download. FED THE PIGS!!
