This surprised me for two reasons. Firstly, I have not seen cubical art here before; as I have never seen the telltale signs of fresh paint not blending into an existing painted surface. Secondly, it’s tiny
In all it’s about 20mm square. It is not by a child as it is too far from the floor and to me has the feeling that it is a caveman painting.
It must be a Macdonald eating Neanderthal man off the Downs doing his weekly shop.
