Description :

A complete brass example of Piet Hein’s iconic Super‑Egg, offered with its original printed instructional pamphlets and fitted green drawstring pouch. Designed by Danish scientist and artist Piet Hein, the Super‑Egg represents the superegg curve, a mathematically derived form known for its ability to stand upright, rock without tipping, and spin with unusual stability.

The brass egg retains its smooth, reflective surface, and the accompanying cards present Hein’s explanations, diagrams, and notes on the geometry and behavior of the form. A strong, intact example for collectors of mid‑century design, mathematical objects, Scandinavian modernism, and sculptural desk pieces.

Market Values & Recent Sales

Recent sales of comparable brass Piet Hein Super‑Egg sets show a consistent range:

  • Brass Super‑Egg with original pamphlet and pouch: $150–$160

  • Brass Super‑Egg with partial paperwork: $90–$120

  • Loose brass Super‑Egg without materials: $60–$85

Complete brass sets with both pouch and printed materials reliably achieve the upper tier of the range, with condition and completeness being the primary value drivers.

Collector Notes

The brass Super‑Egg remains one of Hein’s most recognizable design objects, bridging mathematics, sculpture, and Scandinavian modern design. Its cross‑disciplinary appeal makes it a desirable addition to design collections, educational displays, and curated desk objects.
