Many of these convict cartes held at the NLA are duplicates of the same images held at the Queen Victoria Museum and Art Gallery, the Tasmanian Museum and Art Gallery, and the Archives Office of Tasmania. This simple fact underscores the extensive copying which has taken place since the mid 20th century, principally from the QVMAG collection: 1958, 1977, 1982, 1985, 1987 and most recently for a digital database. Although the Nevin brothers photographed more than 3000 prisoners, the bulk has been lost, destroyed or sold at private auction. The remaining 300 or so were selected or salvaged by Beattie ca. 1916 to sell to tourists; he selected only those prisoners whose sentences were severe enough to warrant a criminal sitting in the Supreme Court: the offender’s apparent notoreity was the selling point. In this respect, the are not a random selection, nor a series. But they were not salvaged because they were an archive held at Port Arthur; they were never held at Port Arthur, nor taken there. Nevin photographed the prisoner once as a single capture in Hobart, produced prints from his original glass negatives at his city studio and later at studios in the Gaol and MPO, and made at least four duplicates from his glass negative for circulation to other prisons and police in regional Tasmania, in addition to the copies needed to paste onto warrants, prisoner records sheets, and the central register held at the Hobart Town Hall. … More National Library of Australia’s convict portraits
