Johto Map Puzzle

I have two of these because I built the first one, and then my dog ate some of the pieces. Years later I bought a second one at goodwill thinking I could replace the missing pieces, completed it, and after my mom got water on it and then dropped it i figured I should bring out the old one to start swapping damaged pieces out. Turns out they make each puzzle unique, so swapping out the pieces isn't even a thing you can do.
