We saw this poster several times on our walks throughout Paris. This is a real estate ad. The headline reads:
Who Owns France?
Chinese, Qataris (from Qatar), Americans,
Russians, Norwegians, Koreans... (more nationalities listed inside)
This is the French way of expressing Equal Housing Opportunity. The side notes are about the real estate services available from tax exemption, to investments, etc.
For us, it is a poignant expression of the world becoming a melting pot, and the affirmation that we all are citizens of the world. We better find a way to get along!
