Handpainted Wall Mask by J. H. Cope. Height 17cm x 13cm wide. James Cope’s Wellington works (Staffordshire) ran for 60 years from 1887-1947. During the 1930s they began producing a range of Wall Masks which used the impression mark of C & Co or C Ltd England, along with a model number. Cope masks were finished with an overall high gloss glaze and crazing finish is also common.
