Here's a real cute mug!
This was made for Sonic 2 in Japan. It's a mug that stars JUST Tails! Having a solo character on something that's not 'just Sonic', isn't that common in this older era. However, it's good move, because look how cute the art is for him they have used. He's super cheerful looking & doing a peace sign (or number 2 for Sonic 2) The Sonic 2 logo is blow him & he's in a ring shape with his name at the top.
The box for the mug is black, with Sonic in a star ring and the logo. The box for all the mugs of this time was the same, no-matter what the design on the item inside was.
The mug itself is a plain, white ceramic with smaller size handle.
What's unusual about this mug is it is VERY Japanese style, the Sonic on the box is, & the Tails especially is. This is something you'd expect to find in Japanese stores, not in England / UK area. (Remember, with their Segaworld they got wierd/ugly Tails art/brown Tails and other errors quickly...this must have appeared before that started happening.
