This is a puzzle where you won't understand the 4th panel unless you've completed it. I bought it, took it out of the box to assemble it once, took a commemorative photo, and then put it back in the box. It was only displayed for about 24 hours, so it's in good condition. Size when completed: 70 x 50 cm Type: Jigsaw Puzzle Number of pieces: 1000-1999 pieces
