When you open the post and fell from the side panels come off. Panel "POST" but as it had been written and I'm not sure if 並Betara restored back into shape.
Sort and get back to its original form the panel.

Notes on Puzzle
You bad person, you. You just knocked off the fancy lettering on Clark's mailbox! Now you have to put it back together. Having just tackled the luggage-in-a-cart puzzle, this isn't very different, except you don't need to rotate any pieces, and there will be blank spots in the panel that spell out the word "POST".
