This shirt is made to celebrate Sonic's 20th Anniversary & promote the main game seen at their booth: Sonic Generations. It has the 20th logo as a small all-white print in one corner. The back has the new Generations title screen/logo seal which features both classic & modern style Sonic in the same pose. This doesn't rule out the possibility of future shirts with this (or similar) design, but this shirt will likely be rare as it was an event give-away. This was a 'swag item' given away at E3 of 2011 at the Sega booth. The shirt itself is dark navy blue, nearly to black. You can see the other give-aways for this 2011 event scattered around the site. As is normal, exclusives such as this are highly collectible, no-matter what they look like. Photo & owned by PiplupFan77
