Sometimes it's not the big things you get at a convention but the little things that are interesting.
Alas... other than the pre-ordered Dogtag I got from Caribou http://www.furaffinity.net/user/caribou/ I cannot remember who I got these items from.

The Moustache pin was cute because the young woman behind the counter made the add-on on the fly, sketching a 'stache, laminating it and adding it to the pre-existing pink-nosed smiley pin.

The DuStable badge was soemthing I felt I should get because well... ponies are in this year and I'd hate to be left out. And because I was helping a friend write some MLP:FIM stories over at Fimfiction.net She referred to me as Abel DuStable and the name was cute enough I chose to use it when I made a profile there.

I love the stone Necklace for the pure uniqueness. I wish to heaven that I could remember the name of the lady who immortalised Abel in glossy dark mineral form.
If you find this, and you know who was doing these at 2012 Anthrocon, by all means let us know.
