The Hildesheim-based artist collective “Kontakt-Kunst,” of which Otto Almstadt (1940–2023) was a member, organized an annual event in Hanover between 1971 and 1974 that lasted several weeks, during which they invited passersby to help create public sculptures. Thus, during the creation of this work as part of the “Street Art Program,” the process—with its emphasis on interaction and communication—was central. Today, the work’s tactile quality invites an intuitive, sensory experience; its abstract physicality hints at the artist’s decades-long studies of nature and anatomy and contrasts the clear geometry of Günter Kämpfe’s adjacent enamel panel with a vibrant texture. Another work in Hanover: “Einschnürung” at the entrance to the Hanover Adventure Zoo. » Location: Theodor-Lessing-Platz
