Antique wood-engraved view of London pointing north from Finsbury Circus towards Islington.
The view was apparently drawn by Thomas Sulman (1834-1900) while flying in a balloon above London. The wood-engraving was done by George William Ruffle (1838-1901) and W.M.R. Quick.
See this cool website on Charles Dickens that uses the Sulman maps to illustrate Dicken's London: www.charlesdickenspage.com/charles-dickens-aerial-london-view11.html
