I started buying puzzles from David over 15 years ago, and I can tell you that this sequential puzzle might just feel like 100 years to solve! I love this particular puzzle so much, that when I accidentally broke my original one years ago, I recently bought two more: one to play with; and the other one to keep in stock! The quality of the wood for these puzzles is excellent. A great Coffee Table puzzle to stimulate your brain.
