Mid Century Mystery: Ceramic Vase? Mug?

Found this unsigned pottery thing-a-ma-jig at the Value Village on Monday. I’m going to put flowers in it but I have no idea what it’s original purpose was. It’s got a handle but no spout, so it’s not a pitcher. Could be a complicated mug. As for the vase option, it’s bigger than a bud vase but smaller than most vases. I’m stumped. If you have any clues, let me know.
