The series of gouaches Aus der schwarzen Kiste (from the black trunk) suggests that you look out of a dark trunk through a keyhole. In the pawn-like recess you look at landscapes in which man has intervened in one way or another.
Here you see a hilly landscape with fences, the contours of a factory looming in the background. Due to the soft pastel colors and the flowing way of painting, the image also has a lovelyness that contrasts with the industrial intervention in the landscape.
