I assembled this puzzle a few times after purchasing it. All the pieces were present when completed, but I have not re-checked them for this listing. I bought it several decades ago, but it is in good condition. I am storing the pieces in separate bags by section, but you can mix them together when you play with it if you wish. I am also listing other jigsaw puzzles, so if you are interested in purchasing multiple items, please feel free to inquire about a discount.
