@nemesisyume & identity I'm with you guys! I miss the photos in the booklets.
It was part of the perks to actually buying the physical singles for me.
@Picaflor 7/4 Here's a shot of one side of my room with the Rule poster (size B3) so you can compare it with other objects in my room. xD It's not very big at all. The BLUE BIRD, Secret and HEART STATION posters that can also be seen are (what I consider to be) normal size. I think they're called A2, maybe B2?
