Check out the first auction listed here today. It’s a nearly three foot statue of Tails from the Sonic series which was used at a Sega convention in the early 90’s. Sure, the price is very high but at least the seller is taking offers.
Mega Man 10 Sealed Press Kit – Taking offers too
Dead Space Engineer Class CEC Wristwatch Limited Edition – #298 of 500
Bioshock Infinite Limited Edition Columbia Concept Statue – 1000 were made
Technos Registrar Patent Certificates – Pretty random, I know, but if you’re a fan of Technos games this may interest you.
