Rare IPP Exchange Puzzle – Jürg von Känel "Outline Burr" – Original Instructions

Offered here is an authentic IPP (International Puzzle Party) exchange puzzle designed by the legendary Jürg von Känel. This 6-piece wooden interlocking burr is a classic example of von Känel’s "non-verbal" design philosophy, featuring the signature grayscale photo instruction sheet provided with original exchange runs.

​Unlike traditional solid burrs, this Outline Burr features a unique "stick" geometry where the pieces are constructed from smaller units to form a hollow-centered frame rather than a solid lattice.

​Designer: Jürg von Känel (likely IPP 21 Exchange).

​Material: Hardwood (Oak/Ash grain visible) with distinct craftsmanship.

​Type: 6-Piece Interlocking Burr.

​Condition: Excellent vintage condition. Pieces are clean with sharp edges.

​Included: Original 5-step photo-based assembly guide.

​This is a must-have for collectors of von Känel's work or those specializing in IPP history. The puzzle is currently unassembled and ready for its next challengek
