NIB Sealed 500 Piece MJ Impossible Puzzle

NIB (new in box), sealed 500 Piece Puzzle "MJ" branding My guess is that this is one of those "impossible" puzzles or "puzzle from hell" types...check the photo, the puzzle's pattern looks to be grey in color with tiny plus symbols all over. Very little detailing; I imagine equally hard to actually put together due to this. Sorry I don't have more info...but I'm not going to open it to find out. Pet & smoke free home
