Colin Ross Designs by James Burgess is a line of ceramic and design objects created by South African industrial and product designer James Burgess for the design firm Colin Ross Inc. For example, they created a small white carton resembling a milk carton which was a vase. 

This ceramic "tumbler" isn't designed for drinking at all, although I suppose you could if you wanted. It is a ceramic reproduction of the old Coca-Cola paper cups, more than likely, to be used as a vase. A display, art etc. It celebrates everyday life of people and the things we know. We think of it as Andy Warhol-ish but usable.
