You have to be careful with puzzles that big. My nephew once got a giant puzzle, 9000 pieces, and it was shipped in two bags. He did not notice that they gave him two bags of the left half and zero of the right half until after he mixed up all the pieces. Then he found that he was solving two nearly identical puzzles of half of the picture on the box, but one was offset from the other by about 1/2 a millimeter. Hilarity ensued.
