This is a fun, interesting puzzle and very well made.
This puzzle is my favorite ever. The pieces are a great size and, they are sturdy and fit well together. The photo on the box is accurate. I did it in an evening as once I got going I couldn't stop. In the morning my wife texted to ask permission to take it apart and start it herself. I found her later that afternoon very happily finishing it herself. We then bought 3 more Galison puzzles, to give as gifts or more likely do ourselves!
