Nintendo has made available the 11.75″ x 18″ Holographic Poster Set on the My Nintendo website. It’s 1000 points to redeem. I had to do some research and find all their ad websites and do their clicky, find-a-thing games in order to collect some points to get to 1000, but I was able to secure one. Be aware: you have to pay $7 for shipping.
Anyway, GO GO GO!!! https://my.nintendo.com/rewards/61b13a290e71d2d5
