Copper engraving, 13.5 x 10 cm, original hand-colour; map of Middlesex from Wallis’ Pocket Edition of the English Counties. James Wallis (fl. 1810-1825) was born in Southampton in 1784, the son of a bricklayer. Apprenticed to John Roper in 1799, he learned the art of engraving. In later life he is variously recorded as a commission and discount agent (imprisoned for debt in 1835), a stationer, and a dealer in beer and wine.
