A black basalt commemorative teapot and cover 1st half 19th century, each side applied with a shell panel, one side bearing a scene of Britannia standing beside an obelisk and Fame inscribing a shield with 'Nelson', the reverse with motifs representing Nelson's three battles beneath a banner inscribed 'Trafalgar', all reserved on an unusual moulded vermicelli ground, 25.2cm.

Cf. Remembering Nelson, A Record of The Lily Lambert McCarthy Collection at the Royal Naval Museum, England, p.185 for similar examples attributed to Elijah Mayer & Son. However, lot 15 in an identical design is marked for John Moseley, suggesting that several Staffordshire factories were producing the same design.
