Excellent puzzle, excellent quality of materials and printing. The assembly does not follow the classic horizontal-vertical placement of the pieces, instead they can be placed in any way and there are pieces with peculiar shapes, which makes assembly difficult but adds a very nice challenge. Of course, this combined with the shades of blue that dominate the background, easily tire you out, so be prepared for frequent breaks and make sure to have good (preferably natural) lighting. However, it is worth its money and more. If you often assemble puzzles, it is a one-day affair.
