I'd like to address some comments that have been made about the puzzle pieces not fitting right. So far, I have found that the pieces fit just fine, if you have the patience to make sure that you genuinely have the right piece in the right place.
I bought this puzzle a few days ago, along with a bunch of foam core board. When it is complete, I will be storing it in pieces until I have the space to assemble and hang it. As with all Ravensburger puzzles, I have not been disappointed with the quality. The pieces are solid and well-cut. There is almost never a doubt in my mind as to whether a fit is correct, but I am very meticulous. Of course, given the size and color challenge of this puzzle, I would imagine that if you are not meticulous, you'd be crazy to attempt this endeavor.
All said and done, I'm looking forward to the next few months. I have almost completed one fourth of a bag (of which there are eight in the box).
If you love puzzles, want a challenge, and would enjoy having some bright artwork as a prominent art feature in your home, definitely buy this puzzle.
As a side note, Amazon.com's customer service is absolutely phenomenal. I very rarely have anything to call them about, but this was one of the rare occasions I had to contact them. I noticed the price dropped significantly on this item the day after I placed my order. They gave me a price adjustment with no hassle whatsoever. This is the reason I have continued to shop with them for... geez, 15 years now!
