Muppet trinket boxes (Midwest)

In 1999, Midwest of Cannon Falls released two porcelain trinket boxes. On one box Miss Piggy is in a bubble bath, with one leg in the air, admiring herself in a hand mirror. A small purple shoe is inside the box. The other box shows Kermit sitting on a log playing his banjo. The base reads "Why are there so many songs about rainbows?", and there is a small rainbow inside the box.
