One of my favorite things about Disneyland is the nostalgic element that it maintains. My dad used to love going when he was a kid, and I like how many of the things he have enjoyed have been maintained as I've gone growing up.
Retro Disneyland! Posters that are in the entrance tunnels to Main Street Disneyland. After you go through the ticket line and see the giant floral Mickey head, you go through one of the tunnels to enter the park and these classic posters are on the walls in huge frames. I love them!
