Here's a cool old glass from 1993. It was produced by "ZAK Glass" as you can see from the raised logo in a circle on the bottom. It has a red & orange checkered backgound, & features the lesser-used stock art of Sonic sipping a straw in a glass while sitting in a director's chair & wearing sunglasses. The back has the logo in a black triangle & a few checkers.

The bottom warns it isn't microwave safe (did they use some kind of metal in the paint? If so, it would probably be a poor idea to drink from it, too)

Glassware like this is usually less common. First, it's glass and it's for kids, so it gets broken. Next, the designs on old items like this were painted on, and generally not dishwasher safe. The designs can chip, crack, peel, scuff & generally wear until it makes people want to throw it out. (Note hairline scratch through N of logo) Holding onto collectibles like this is a good idea as they age.
