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
