Ceramic "Drip and Drop" Salt and Pepper Shakers

Here is a whimsical set of Salt and Pepper Shakers that were made circa the 1960's. . I believe one is called drip and the other one is called drop. One measures 3.5" and the other 2.25" tall. One looks mad and the other one looks sad. The condition is very good, maker is unknown.An unusual set for your kitchen collectibles.
