The bill headings of John Howard show both his retail premises and his foundry. The depiction of the foundry is less idealised than some, with copious black smoke billowing from the chimneys and the load for the wagon in some disarray in the courtyard. The shop (or warehouse) appears to be elegant, however, with the window display being admired by a fashionable couple. It is notable that the (signed) engraving was made in London by a well-known firm of engravers, rather than locally. Other examples of the work of Reeves and Hoare are at nos. 65 and 331.

John Howard’s bill heading is unusual for the very detailed description of his wares and the breadth of his work in all types of metalworking.
