I purchased this when it was first released and have taken great care of it. The 20th Anniversary edition includes four postcards and two posters. The Switch version includes one bonus postcard. The Japanese version is not the first edition. I opened it to check the contents, but it is unused. Postcards are also included. I am also selling this on other sites, so please comment before purchasing. I have discounted the price for a limited time, from October 10th to 13th.
