A look at one of the works inside the Oppenheimer Villa. This one really appealed to me, I love the textured brush strokes and the way the yellow lights seem to glow in contrast to all the grays.
Here's a better overview of the work. It's called Zur Grube or To the Pits and shows the miners on their way to another day's work. This work was painted by Berlin artist Hans Baluschek. Photo taken in April 2012.
