Here's a cool promotional bag that shows that Japan isn't the only place to create fancy bags. This promo bag is from EB Games of Australia. If you bought any game around the time of the release of Sonic the Hedgehog 360, it would be placed into a bag like this.
The front has a huge all-over Sonic face, which makes for a neat design. The back has the 15th anniversary symbol, the logo for Sonic and also Sonic Rivals. This is a rather cool collectible bag.
