East Riding. The Universal Magazine featured 2 separate sets of county maps during its lifetime - the first between 1747 and 1766, and a second set from 1791 to c1797. Most of the second set of maps were engraved by Benjamin Baker (who later went on to work for the Ordnance Survey). This is one of the 5 Baker maps of the county and Ridings of Yorkshire. The maps were subsequently re-issued as a complete county atlas, publsihed by Darton and Harvey in 1804, and then by Laurie and Whittle and their successors from 1806 to 1846. This example of the East Riding map is from the Universal Magazine set in the 1790's.
