[n.d., c.1790.] Engraving. Sheet 160 x 120mm (6¼ x 4¾"). Trimmed within plate, laid on album paper. Diagrams of ship's instuments invented by Valentine Gottlieb, an immigrant who settled in Lambeth in the 1770s. He successfully lobbied the government to install his design of a mechanical perpetual ship’s log to two newly-designed fast postal packets commissioned in 1790 for the North American and West Indian mail service. The December 1791 issue of the European Magazine contained a variation of this engraving plus explanatory text of this group of related navigational instruments.
