A pencil sketch on paper, 13 cm x 14.2 cm, showing some houses and trees. It is unsigned but by the style, it can be ascribed to Rolf Keller. It is a typical feature of Tolf Keller’s style to draw objects, e.g. trees, with one or a few long convoluted zigzag stroke.
There is a caption in the left lower corner but I am not sure about how to read it. It seems to say “Anlage zu 5″ (attachment to no. 5), but I am not sure if that reading is correct and if so, from which context it has been taken. It might have belonged to some letter. There are some letters of Rolf Keller that I have not evaluated yet, so it might be possible to find the context into which this belongs, but maybe that context is lost. I cannot, at this time, identify the buildings shown here, not do I know the time this was drawn (maybe the 1920s or 1930s).
