Here are 2 small glasses from the Team Sonic Racing bonus game pack. (Game pack seen on Japan Electronics here on Gear) These glasses are likely to be 'shot glass sized' but they are called 'mini glasses'. They both have the game's logo embedded in the bottom thick part, one is red, the other is blue. The edge is made to look like a car speedometer. They also have frosted glass details on each side. One is Sonic in the Speed Star car, with a 'trail' behind it as it drives toward the viewer. This side circle logo has the Speed Star in it and the word "Sonic Speed" at the bottom.

The other has Shadow in his car & that circle graphic has "Dark Speed" written in it. So each one has different graphics throughout--it's not just 2 things in 2 colors. Shot glass collecting is a popular thing to do, even when they are never used to do shots. With 2 designs per glass, and colorful bottom logos, these glasses really have a good and thoughtful all-over design. They're a cool collectible...and likely to be uncommon if the bonus pack is the only place they can come from. 

The graphics above show the designs as they are planned / not on the glasses. The etch is by it's very nature monocrhome (etch and not etch areas) and the 2 glass bottoms with their colors. The graphics are nice to see because all types of glass items, by their nature are difficult to photograph.
