This item may be the only one of its kind, so certainly it's exclusive. It is a Sonic figural trophy for what's likely a Sega sponsored car race somewhere. The winning driver got the trophy which looks like it might be some type of metal? Whatever it is, it's big, and likely heavy as it has fuzzy felt feet on the bottom. The front has the Sega logo in blue, and a uniquely posed all 3D Sonic standing next to a trophy-cup with shiny rim. It looks like he's holding one of the handles, and has a foot up on its base.
The race was in 1993, it was the "F1 European Grand Prix", in Donington Park
Were there other Sonic themed trophies for 2nd, or 3rd? No. But Sega sponsored the race, and that year the race was known as SEGA European GP. No other year had a Sonic trophy because 1993 was the year SEGA invested the most in marketing, and the only year that they sponsored a race in.
Who won it? Ayrton Senna, the Brazilian racer from the Mclaren-Ford constructor.
The material the trophy is made of, as well as its location today are still a mystery.
What an interesting item.
