The artist Zoltan Kemeny's space sculpture of 1963 in the glass foyer of the Städtische Bühnen (Municipal Stages) in Frankfurt am Main shapes the face of the building. The over 100-meter-long artwork, which is visible from afar, sets a contrast to the architecture of the building with ist organic dynamics and accentuated handcrafted quality. Based on new research, the book presents the artist, artwork, and genesis and reception of the work, which is beloved by the residents of Frankfurt, in texts and images. New student designs show various options for how the presentation of the recently landmarked work can go hand in hand with a conceptual revision of the Städtische Bühnen.
