Charming miniature plan of London in the early 18th century

A miniature map of London with the layout of the streets but only the Thames named. At the bottom are the Royal Arms with allegorical figures of the Thames and Britannia; above are the arms of the City.
The map was published in the 'Atlas Portatif, ou le nouveau Theatre de la Guerre en Europe; Contenants les cartes geographiques, avec les plans des Villes & Forteresses les plus exposees aux revolutions presentes'.
