I found this mural of a jester on a building in the Ipe Brouwerssteeg in the centre of Leeuwarden.
A jester, court jester, or fool was historically an entertainer. In medieval times jesters entertained in a wide variety of skills: principal ones included songs, music, and storytelling; additional ones included acrobatics, juggling, telling jokes, and magic. (from Wikipedia)
The mural wasn't signed and unfortunately I haven't been able to trace who made it. I like it a lot though!
