Bukowski tattoo

So my sister had this very life like tattoo done yesterday on her thigh. It's of Bukowski. The very talented Milan didn't cease to amaze with his skills at Eagles Wing Manchester. If your Manchester based and want done seriously good art pop down. There in Shudehill (by the bus station) and are open 10-6 Monday to Saturday :) 

How????

This performer 'sits' in Market Street in Manchester but how does he do it? That's not a riddle it's an actual question?
