Set of extremely detailed maps. The first is titled "A General Map of Saxony and Bohemia, With the adjacent Countries, including all Silesia, Being a Specimen of a new Geographical and Military Atlas; to be continued occasionally", the other three untitled. This is part of an ill-fated project begun in 1760 by the Gentlemen's Magazine intended to provide a detailed set of maps of Germany. These were to be issued over several publications, partially to boost sales of the magazine. The project was never completed, as only 16 of the 41 maps were produced. This set includes the first four of the series; the General map, No. 26 (with Freyburg and Troblitz), No. 32 (with Dresden), and No. 20 (Prague). All folding as issued.
