In Copenhagen many of the older house ends are painted. It can be a naturalistic painting, an add or more abstract like the one above found in Gl. Kongevej (Old King's Road) in Frederiksberg. A great idea to cover otherwise dull surfaces in colours and forms instead of just giving them one colour (which of course would be a shade of grey). Some of these paintings was in fact made by artists like Henry Heerup or Hans Scherfig. Many of the paintings disappear over time due to neglect, smog or demolition, or they're covered by new owners who like something else.
