A Martin Brothers double-sided stoneware face jug circa 1890, modelled in relief by Robert Wallace Martin with a whistling face opposed by another with a sneering expression, each with white-highlighted eyes, incised marks to base, 15 cm high. Provenance: Part of a single owner collection originally acquired directly from the Martin Brothers Pottery, by Samuel L. M. Avery Esq., a master builder and resident of Southall. Avery was a friend and acquaintance of the Martin family, often visiting the pottery where he bought pieces directly from them for his own collection. The collection was inherited by his descendants and has remained in the family ever since, only being recently discovered following the passing of his daughter.
