This is a bonus postcard from the 2019 Kamen Rider movie. There are 20 Kamen Rider postcards and a second postcard with Build, etc. 24 cards in total + unopened! If you would like to confirm that all cards from 1 to 20 are present, please comment and I will add photos. I collected all of these myself, so they haven't been handled by multiple people. I stored them in a file after purchase, so there is no sun damage. However, please understand that they have been stored by a private individual.
