Well I ve got these two posters on the back of my G1 shelves. BUt they fell off ( ive only used blu tak) so I stuck them technically not a wall but the door of the closet in my collection room since the wardrobe is a whole wall



they kinda ended up hidden at the back when the figures got on so I didn't regret transferring them when they peeled off.




and in my bedroom ive got these two framed prints right above my TV
