The front with a view of the Newcastle Exchange Spire, the reverse with barber scene, inscribed "Ino [John] Cubitt, HairDresser, No. 25 London Lane, Norwich, Aug.t 11 1788, N. Spilman, Fecit." The hairdressing scene is wonderful and quite unexpected.
Other horn beakers by Spilman are in the National Maritime Museum, London, U.K., and the Brighton Museum & Art Gallery Royal Pavilion Gardens, Brighton, U.K.
The last image show this beaker next to another Spilman beaker - that one carved for The Society of Universal Goodwill. Link here.
