I'm interested in hearing about and seeing pictures of the kinds of space-related geegaws, doodads, mementos, and other artifacts that other space nuts have collected!
Here's one to share to start things off. In September 1969, my dad went on a VIP tour of the Manned Spaceflight Center (now Johnson) and Kennedy Spaceflight Center. (He got to see Apollo 12 being assembled in the VAB! I'm trying to get copies of his slides.) Anyway, one of the things he was given was this 15 inch by 22 inch (38 x 56 cm), three-dimensional, vacuformed plastic replica of part of the model used for lunar landing simulator trainers. This is a part of Apollo Site 3, in Sinus Medii. The raised surface depicted is roughly 650 meters on a side, too small to be seen in the Apollo 10 photos of the area. I have not been able to find Lunar Orbiter photos of the area. There is no vertical exaggeration in scale.
