Manhattan unfurled
A guy named Matteo Pericoli did the artwork for the new Beastie Boys album, To the 5 Boroughs. The album cover is just a small selection of two 22-foot long pen-and-ink drawings of the Manhattan skyline. Pericoli's website has a scrolling version of the entire piece. The detail in this drawing is just incredible.
It looks like the Beastie Boys are also using Pericoli for their animated ecards (links on the left).
