Hanging tough

Still can't quite work out why this piece of art has been resting on my radiator (which by the way will not be heating up until December 15th) for a couple of weeks. I've been to well over half the cities with only a couple to go until it's a full house. Hopefully it'll be on the wall soon in replace of the 'art' currently up from the wee Nephew. Well when I say art I mean a sheet of A3 covered in random felt tip pens that apparently looks like a rainbow....
