Too much stuff really...
Disney pins (and Disney LPs... and sometimes PVC Disney figures... and Disney movies, basically...)
Toys of ice age animals
Fossils of ice age animals
French-Canadian finger-woven sashes
Shinto prayer plaques from the different places I visited in Japan
And stuff from the video games Bioshock: Infinite and Sakura Taisen... And some vintage Nintendo stuff... and some Universal Monster stuff... And a lot of books... So many books... I'm actually trying to cut down and clear out stuff, frankly. This didn't even include the accumulated bric-a-brac...
