A view from Quedlinburg. This colored drawing was made by Rolf Keller during a trip in the 1950s. Parts of this town, situated just northeast of the Harz mountain range, are now on the UNESCO World Herritage List.
This drawing is framed and under glass, so it was a bit of a challenge to get a good scan of it.
A watercolor showing the “Schrammsteinmassiv”, a famous group or rocks in the Elbe Sandstone Mountains, made by Svend Keller on June 7th, 1949. The Elbe Sandstone Mountains were one of Svend Keller’s favorite landscapes and there are several depictions of motives from this area made in different techniques (see https://kellerdoscope.wordpress.com/?s=Elbe+Sandstone&submit=Search).
