My soup

I could not believe my eyes when I saw this typical American school bus in the streets of Paris (actually the Boulevard Hausmann) today. Of course it's not a real bus, but probably some advertising material for Longines, as the sign above the windshield shows it. Later tonight I also saw it at Place de la Concorde. What I don't really understand though, is that its licence plate is from Québec in Canada. I seriously doubt they brought this bus all the way from there, just to advertise for Longines in the middle of Paris...
