Very Challenging Puzzle 3D, 620 sturdy foam-backed pieces assembling into a castle. The design is named "Camelot."
The puzzle was assembled to verify that everything is complete (see pictures).
Some of the pieces show slight damage from previous use. A few were repaired. Overall, this puzzle is still in good condition.
The box seems to have served as a shipping box originally. there is a shipping label attached and shows some obvious wear and taping.
