Query: Very difficult puzzle.

This is a beautiful puzzle but very challenging. The colors are not distinct enough to distinguish which pieces go where. Having put many puzzles together before this, this one has been the hardest ever. You can sit for an hour and only find a few pieces. Yes,it is that difficult. It is a large puzzle so be prepared to have a large working area occupied for a good length of time. The pieces do fit well together but do not fit as you might expect. The shapes are very different. If you want a challenge then this is the puzzle for you.
