Here is a pair of Sonic Generations pin-buttons. These simple, carded buttons were given out at the Sega booth at E3 2011 as part of the 'swag' (or gifts for guests) The buttons have similar (But not the same) Green hill style backgrounds, but each has a different 'era' of Sonic on it. The card backing is nice as well, with a washed scene from the game background. Being exclusive to E3, these are a great collectible item!
