NOTES: Mabie Todd & Company, famous for Swan pens and ink, began producing dip pens and mechanical pencils in New York City in the 1840s and took out its first fountain pen patent in 1878. A London office was opened in 1884 and the manufacture of pens in the UK began around 1909. The Company's prosperity declined after World War II and production ceased before the end of the 1950s.
NOTES: The Post Office (London) Railway Bill was passed by a Select Committee of the House of Lords in 1913 which reccommended the construction of an electric railway with driverless trains to connect the West and East ends of London. Construction of the tunnels began in 1914 and was completed in 1917. The operating equipment was not installed until after World War I and the railway finally opened on 5 December 1927 with parcels traffic running between Paddington and Mount Pleasant. The line was extended to Liverpool Street on 2 January 1928.
NOTES: The Monument, a colossal Doric column, stands at the junction of Monument Street and Fish Street Hill in the City of London. It was built between 1671 and 1677 to commemorate the Great Fire of London and to celebrate the rebuilding of the City.
NOTES: James Ayton Symington was the illustrator of county guides and children's books, and this particular topographical drawing is one one of a number drawn between 1890 and 1897 depicting English market places. The drawings were probably intended as illustrations for a book or article but were possibly never published.
