Street Art en Paris

Walking, cycling around Paris I couldn't help but look up at the beautiful traditional architecture of the small alleyways and winds, often to see street art plastered on the ends of buildings. Reoccurring was that of the Space Invador and a few of Banky's pieces, although many others existed, along with much more graffiti like art.

Other artists make their mark:

This is only a taster of the art displayed around the busy streets of Paris. Interesting to see opinions of what they think is art and what is graffiti. What do you think?
