“The Countye Palatine of Chester with that most ancient citie described” from The ‘Theatre of the Empire of Great Britain’ by John Speed (1551/2-1629), first published in London in 1611. Speed’s atlas of Britain included maps of British counties.
The map has a rather large inset of a map of the city of Chester and vignettes of the coats of arms of the Earls of Chester dating from the Norman conquest of England.
