This is part of a Clementoni series of puzzles with what they call a “wood-effect”, and on the box it even says “Wood Puzzle”. It’s not of wood, though, just ordinary cardboard, and the “wood effect” consists of the pieces having grooves that make it look like wood:

I know I’ve said many times that I’ve never met a 500-piece Clementoni that I didn’t like, but I’m afraid that run came to end with this one. The image (of Venice) was darker than on the box, and the grooves affected the fit, so that it was difficult to know whether a piece belongs or not. Good thing I got this cheap. It seems the series has been discontinued, and I won’t be getting any more of them in any case.
