A similar example, together with a larger mug, is illustrated in Diana Edwards and Rodney Hampson, White Salt-glazed Stoneware of the British Isles, p. 96, fig. 91, where the authors discuss the uncertainty of the commemoration and further state that the mug could possibly be an anti-Jacobite one, declaring loyalty to the King. Other similar examples are illustrated in Bernard Rackham and Herbert Read, English Pottery, pl. LXXXIX, fig. 159, and in the City Art Gallery Catalogue, The Incomparable Art, English Pottery from the Thomas Greg Collection, cat. no. 119. A larger, similarly-decorated example was sold in these rooms, December 9, 1986, lot 29.
