this is the I Amsterdam sculpture in amsterdam (actually, there are 3, one at the museumplein, one at the airport and the one above, which apparently changes location every now and then. here its in amsterdam north. the entire sign says "i amsterdam", with the i am in red. climbing is optional. a small note on the side of the sculpture actually says that climbing is at your own risk and that its not made for that, but everyone does it anyways. not like similarly large sculptures in the US, where climbing is not allowed and where that is strictly enforced (like with this sculpture that was really a huge climbing temptation for many).
the girl crawling around on the top had some trouble getting off the sculpture again, but not before her mom had taken several pics!
