Double-sided Puzzle Framing

We are proud to frame one of the "World's Most Difficult Jigsaw Puzzle". It is a double-sided puzzle, and the picture on the back is a 90-degree rotated version of the front!

Of cause, the frame must be able to display both sides of the puzzle. So, we sandwiched it in between two acrylic sheets and make it stand on the table.
