Cela n‘est pas un arbre...

...it’s a sculpture by Vera Röhm, in front of Darmstadt Museum. A type feature of Röhm‘s works is the implemented acrylic glass, first produced in Darmstadt in the 1930s by the Röhm factory which still exists. Here the acrylic glass sits in the middle of the sculpture, so connecting its two halves and allowing a perspective at the same time.
