If you live in London, then you will definitely know about this artist, but if you don't, you do now! I first saw Conor Harrington's work about 2 years ago and have been a fan ever since. His skills at Realism are untouchable and the great thing is that he can do it with a tin of spraypaint just as easily as a brush. Mix it up with some abstract lines/shapes and you got a winning formula IMO.
Check his WEBSITE to see more amazing work, both on the street and in the galleries.
