"...most definitely it wouldn't work on a general touristic place"? That's a pretty strong statement to use with no proof.
The sites that the National Trust maintains are "general touristic places". It's the UK's largest membership organization, with a membership of 3.7 million people in 2010. It owns over 200 historic houses. It owns more than 630,000 acres, nearly 1.5% of the entire land mass of England, Wales, and Northern Ireland, and owns or protects roughly 20% of the coastline.
One of its properties -- just one, and remember that it owns over 200 houses and 630,000 acres of land -- had nearly 440,000 visitors in its 2009-10 fiscal year.
National Trust properties are most definitely "general touristic places" at which these signs are working.
