Mug with manual alphabet.The mug has no maker's mark, but a similar earthenware mugs from Staffordshire with what appears to be the same sign transfer pattern, have been dated to the early 19th Century, c. 1820-40. Note how the 'Q' differs from the later sign alphabet (Action on Hearing Loss Library).
The mug was donated to the Library by Mrs P.J. Bierschenk.
