Great resource material and fun maps from (and yes the name may be too much for some but . .) fuckyeahcartography on tumbler. If you love maps then you might want to follow this user as they always have some fun stuff to share.
Above is One of four maps which tell a fascinating story of the built environment of our Sydney in late 1880s.
They outline buildings with a colour code denoting the building materials used and provide the name of the building and sometimes the proprietors.
Go to the catalogue record where you can zoom down into the streets.
See how Sydney’s buildings looked 50 years later by going to the block plans of the 1920s and 1930s which were similarly surveyed by the Fire and Accident Underwriters’ Association of NSW
