This is an antique Sowerby pressed glass posy trough or planter.

It features the "Elizabeth, Elspeth, Betsy & Bess" pattern, which depicts characters from a children's nursery rhyme book illustrated by Walter Crane.

The item is made of blue milk glass (also known as vitro-porcelain glass).

It was manufactured by the British company Sowerby in the 1870s and appears in their 1882 catalog as pattern number 1219.

The base bears the Sowerby trademark of a peacock.
