These molded miniature figurals of a matching pair of booties or shoes are made of English pottery, or earthenware - they are not glass which you had posted as the material. These were produced by the Royal Art Pottery and date to the mid 20th century. They are a 'take' on the nursery rhyme of the Old Woman Who Lived in a Shoe. These were used as small planters, decorative wares, toothpicks holders and the such. The estimate is for both together based on actual recent past recorded auction sales of comparables.
