Dodecahedron (DDH 3) is number 7 in Robert Rose's esteemed series Mental Block Puzzles. It consists of a sturdy dodecahedral core with 12 small circular protrusions and 12 pentagonal jigsaw pieces that you must fit around the core. "MBP 7 DDH3" engraved on one side.
This piece has never been used, and the 12 pentagonal pieces are still tied together as when they came from Rose directly. It is in pristine condition.
This puzzle comes from the collection of the late Saul Bobroff, which we are selling on behalf of his widow, Paulette.
