Oh boy, I've got quite a few things that I'm quite proud of owning. My vast autographed CD collection (including releases from both professional bands like Linkin Park, Kamelot, and Celldweller, and brony artists like Eurobeat Brony, Cyril the Wolf, and Aviators), my numerous traffic lights and highway signs (including a pair of 1970's Soviet pedestrian signals, pictured)...it'd be really hard to narrow it down to just one thing.
