A scarce antique road map from "An Actual Survey of the Great Post-Roads between London and Edinburgh" by Mostyn John Armstrong, published in 1776. Each map shows a section of the road from London to Edinburgh drawn on the scale of half an inch to the mile. These maps are not strip road maps, but take the form of a conventional map covering an area of approximately 12 miles from south to north and 7 miles east to west.
This is Plate 33 - Prestonhaugh, Haddington, Tranent Moor.
