This came in a lot and I'm curious who it is. I don't think it's particularly old or of quality, but would be interested in your thoughts.
Seems to be houses and other shapes painted in an expressionist style ( if I'm being charitable! ). There is a signature but I can't make much headway with it, maybe beginning with a T or K. Nothing on base, but I have included a shot anyway. 20 cm height.
