This is a classic. It’s by Jef Aérosol (the pseudonym of Jean-François Perroy, a French stencil graffiti artist). He has been an urban art proponent in France since 1982, and is a contemporary of Blek le Rat and Speedy Graphito.
You’ll find it by The Pompidou centre behind a pond full of crazy fountain sculptures in Place Igor Stravinsky. Well worth the detour.
