To my mind this type of puzzle should not be regarded as a toy, or if it is, it should carry an age rating of 12+. Having said that, I love these puzzles. Made to typical Ravensburger quality standards, the pieces fit well and the finished product looks impressive.
Other people reviewing puzzles complain of a missing piece. I found that when I emptied the bag and completed the puzzle that I too had a piece missing. But after a thorough search I found it, not on the floor as I expected, but in the pleated corner of the bag where I could not see it, but luckily felt it as I was throwing the bag away, something to be aware of in the future.
