This collection of pictures is taken long before RRL started with it's mugshot inspired lookbooks.
In 1990 the Australian Historic Houses Trust rescued a remarkable collection of NSW (New South Wales) Police forensic photographs from a flooded warehouse in Lidcombe. Created between 1912 and 1964, the archive contains approximately 130,000 glass plate negatives depicting crime scenes, police activities, forensic evidence and mug shots and may be the biggest police photography collection in the southern hemisphere. The Historic Houses Trust has the job of conserving, repackaging, digitising, researching and cataloguing the archives contents, for which original record systems have been lost. You can find the story behind these pics and even more of them at Twisted Sifter.
