This sign was outside the Musée de l'Armée in Paris. The phrasing was weird which is why I took the pic.but my attempt to take a second picture of where actually on the lawn this sign was located was strongly discouraged by the French soldier with an assault rifle. this was about 5 feet from their security booth as you walk onto the grounds. In the states there are few "stay off the lawn signs" the main method of keeping people off the lawn is an angry older person wielding a bat or gun screaming at the top of his lungs " HEY YOU BASTARD KIDS GET OFF MY LAWN!"
