vintage China blue & white porcelain napkin rings, set of napkin holders w/ tiny monkeys

80s vintage chinoiserie porcelain napkin rings, made in China. These look at first glance like a pretty traditional blue and white pattern, but when you look closely, you see that the pattern is made up of tiny monkeys!

This is a set of eight, all in very good condition, gently used, no damage. They measure about 2" across the opening, 2 3/8" overall.
