My girlfriend took me to a gallery solely dedicated to Voutch which she had found on a street in the north west of the city. It's a small space but they sell many of his original paintings none of which I could afford to buy (they start at 900 euros) but it's great to see them for real. They're quite small too, most no bigger than A4. They also sell his books of course & posters & postcards too. Voutch heaven! The gallery is on Rue Guersant, Metro:Ternes.
