Here is a mug exclusive to Sega World Sydney.
It's a white ceramic normal mug, with wrap-around Sonic graphic. It uses forward facing Sonic, but what's he doing with his arm? He has one arm bent but kind of back behind his spike? The other has the 'finger waving' position for his hand. He's shown winking, which is fine because he's winking his whole actual half the eyelid and not mysteriously 'his pupil' somehow.
The main thing to note here is the background, though, which has the famous bridge "The Sydney Harbor Bridge", which is unique to the area (no similar bridge) and also a tourist attraction because supposedly some part of it is climb-able if you pay. This mug is most certainly doing it's job as a souvenier from the SWS & the city itself by mixing in Sonic. It is uncommon. This is thought to be a factory photo.
