Two small pressed horn seals in the shape of Wesley busts, each with mother-of-pearl preaching bands. This particular seal appears to have been very popular; the museum owns several and occasionally one comes across them at collectors fairs and online.
Interestingly, the right-hand seal is more detailed and the modelling crisper than the left. Although both are by the same manufacturer, it is possible that a different mould was used in their production, or that the existing mould had been used many times prior to casting the left hand seal. This would have resulted in poorer detail.
