A Flickr Photostream
Browsing through the impressive collection of mug shots from Least Wanted, aka Mark Michaelson is a fascinating trip. I added a few favorites here, but really, you could spend a big chunk of your day going through his flickr albums (and I recommend you set that time aside).
He published portions of his collection in a hardcover book also called Least Wanted and currently creates eye catching street art based on the images.
But what do you think?
