What's this!
It's a Sonic the hedgehog cabinet! This is a black, rolling cabinet likely made of pressboard coated with black finish. It has 4 little wheels & 2 holes in the back, likely for cords. The bottom has a door that opens downward. This door has a gold-tone Sonic title-screen graphic on it. The 2 other shelves above it are on pull-out rollers (see middle photo.)

Note the shiny brass looking bit at the top edge. The far right photo shows you a close up of this metal embossed item, it's a Sega logo that's been nailed on by the furniture manufactuerer.
This cabinet is a bit of a mystery. What is it for? Is it the only one like it/especially made JUST for Sega or used by SonicTeam? It's clearly for electronics of some kind. When it was discovered at auction, someone certainly beleived in it because it sold for about 3,000 USD. If it is one of a kind, this is a great photo set so see a really cool old Sonic furniture piece!
