Space Invaders in Paris 015

Some say the aliens arrived on earth centuries ago.Well, it's hard to say when this camouflaged Space Invader landed here. The wall was built in the 17th century. 15 years before the French revolution, the building hosted the first public library in Paris. And the writer Alphonse Daudet lived here in the 19th century.
