Blacklite posters with a Wonderland theme (plus a few others), though I haven't added to it in a long time.
I like antiques. The way many products made several decades ago work better with more endurance than something pooped out by a corporation today (and yet may have the audacity to charge more for it than an antique in good condition) only adds to their appeal. When I find my "retirement place" (still debating where that's going to be), I'm going to invest a lot in antiques.
I've actually got what I need for a desktop that's 20 years old save a box screen monitor, and I'm only preparing to get a new computer, reluctantly, because I've been unable to get the proper monitor from a place or person I trust. And if I ever get another vehicle, it will be 20+ years old, and assuming good maintenance, I'll assume it's better (if fewer toys) than anything just rolled off the lots today.
