This is a very interesting puzzle manufactured by Clementoni. The title is Palace of Illusion, by Irvine Peacock, although there is no reference to the artist in the box. It is obvious that this painter got inspired by Escher when completed this work.
The puzzle is USED and COMPLETE, as it can be seen in the photograph of the puzzle assembled. The actual piece count is 1488, as it is common in many Clementoni puzzles.
There are a few pieces showing a bit of wear, as shown in the pictures. One of them is glued as the top layer of one of the lugs, which had come off. This is really the only one that is barely noticeable upon completion. Slight crease on the adjoining left piece and on a piece near the bottom, but they are really difficult to notice.
The box is in good condition, but does have a crease down the front & a small puncture at the end of the crease.
