This outdoor art installation was presented in celebration of Liberation Day in the small town of Leiden, the Netherlands. This functioning wood urinal was made by a "sculpters collective 'Kunst Uitschot Team'", which can be roughly translated as "Art Scum Team".
This photo was sent in by a memeber of the Kunst Uitschot Team. He writes: "In The Netherlands you get a 60 euro fine for urinating in public; well not if you urinate against this tree!"
