"Bein mit Kupferklammern" (1985) is a sculptural work by German artist Joseph Beuys consisting of a leg form bound with copper clamps, exemplifying his characteristic use of unconventional materials to explore themes of constraint, healing, and the body's relationship to industrial materials. The piece reflects Beuys's broader artistic practice of addressing trauma and transformation, drawing on his personal history and his belief in art's redemptive potential. The copper clamps simultaneously suggest both medical intervention and forceful restraint, creating an ambiguous tension central to Beuys's conceptual approach.
