Almost everyone has something they like to collect or they might have a few item that they love for what ever reason such as an autograph of one of your favourite celebrities.
I have a heap of autographs from celebrities I've met at 'Armageddon Expo' the last few years. Mostly Stargate actors (Michael Shanks, Ben Browder, Paul McGillion, Joe Flannigan, Jason Momoa, Torri Higginson) but also John DiMaggio from Futurama. I also have my pictures taken with almost all of them.
Just recently I acquired what I consider to be some rare Pokemon Collectables. A Celebi and Deoxys distribution cart (Picture). The Deoxys cart is the cartridge used to give out the GameStop Deoxys from 2008. The Celebi cart is the Winter 2011 Celebi (also given out at GameStop stores).
So what's in your collection?
