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 look at a tripod of bamboo sticks under which a flowering plant stands. The oblique cut-off on the left in the image is difficult to indicate, is something being slid in front of the keyhole or is it positioned further away from the trunk ?
