One of the better painted Mr. Yodel yo-yo models. Side A has the Mr. Yodel 2000 side cap; side B has the glitter "ProYo II" side cap. It's not clear what the "/91" stands for.
The painted inside rim in black and white animal-type stripes is quite beautiful.
These handpainted yo-yos did not come in or with any packaging; they were sold standalone.
