Because of the building of a coal plant from a big energy company near de Waddenzee in the North of Holland there would be a high risk of losing this famous Dutch piece of nature. To make tourists and visitors aware of this problem, we put a few photo booths on the coastline in the North of Holland with the Waddenzee in the background, so you could make a ‘last’ picture as a souvenir, to remember the Waddenzee if they would disappear in a couple of years. The photo was a postcard which you could send out to the energy plants as a deregistration.
