Detail from a set of bed hangings. Although a paper impression of this design is inscribed P.33 Talwin & Foster 8d, the pattern was not necessarily produced only when the Bromley Hall factory was operated by the Talwin and Foster families (c. 1783-90), as other impressions of the same design have no inscriptions, and many copperplates were used for twenty years or more. The three blue threads in the selvedge of this piece indicate a date between 1774 and 1811. Dilys E.
