Focus on this artwork and analyze the Variations.
Two foundries (Seiler in Germany, Powderhall in Scotland) still produce faithfully accurate editions of the statue. These editions differ in size (13cm and 30cm, respectively) and patinas (a light traditional bronze, and a much darker penny bronze, respectively).
Other versions less faithful to the original mutate the chimp's pensive contemplation to head‑scratching bewilderment, or sacrifice metallic lustre by substitution of cheaper materials (e.g., clay), and often undermine the sculpture's poise with careless positioning of a plastic skull. Prices currently range from $10 to $4,500. When they do rarely surface in auction or through private sale, Gladenbeck pieces can fetch up to $6,000.
