Some of that was free, some of that was traded, and some of that was bought. Not a bad deal there though, and I'm happy with my yield.
The crazy ax on the left is from Crazy Bricks' Munchkin stuff, as a prototype. Winners of my Munchkin card games Thursday afternoon also won a grey prototype piece! The specialty weapons are either from BrickArms (they have some cool sci-fi guns if you look past the young kids fawning over the military stuff), BrickForge, or BrickWarriors.
I also got a Star Wars planet for a dollar, for another hot air balloon. I was also able to get a pack of the Studs trading cards which included a few favorite builders of mine, so that was a win!
I don't know where that white smiley minifig head is from (help!), but I'm sure it's worth more than I paid for it.
More BrickFair stuff to come!
