The Dictionary of Sydney was launched on 4 November 2009. It’s an on-line encyclopaedia of the history of Sydney with new material being added continually. The range of subjects is broad and sometimes surprising. Along with such conventional topics as, say, Governor Lachlan Macquarie or the Japanese Submarine Attack, there are such entries as Drag and Cross Dressing, and The Royal Commission into Noxious and Offensive Trades, and even (ta-da!) Reading the Roads.

‘Poke’ is one of the illustrations for that article. It’s an example where unofficial graffiti – an advertisement for a dance party – has colonised a piece of official pavement graffiti – a zebra crossing. The photograph was taken in Newtown in 2003.
