STC 39 Rosebud is a co-ordinated motion polyhedral puzzle which is difficult to make and difficult but not impossible to assemble without the aid of a jig. When perfectly aligned the six pieces slide together and open and close like the petals of Rosebud. The Rosebud Assembly Jig is sold seperately and is highly recommended.
Stewart himself says "A few of these puzzles were produced some years ago and sold unassembled. After sufficient time had elapsed and almost none had been solved, the customers were given the opportunity to purchase (for an outrageous price!) an assembly jig and directions. With these, it is easy. Without the jig, it can be done with patience, using tape and rubber bands. Without such aids, it has been done but borders on the impossible."
This version is finely crafted from American Black Walnut and beautiful red Bloodwood . This is a rare puzzle and highly collectible.
