Internal evidence suggests they were taken in the mid- to late-1990s by someone with a passion for South Australia's colonial architecture, from workman's cottage to squatter's castle, as well as the more commonly recorded churches and public buildings. Although this extensive gallery of our built environs is not yet twenty years old, it is already looking in parts like a revised edition of Michael Burden's 1983 classic work, 'Lost Adelaide'. The photographs (either 100 x 160 mm or 95 x 150 mm) are in very fine condition, easily removable from the album leaves (hopefully they are indeed 'acid free card with alkaline glue and polypropylene overlays'). The places depicted in each album are noted in order on adhesive labels on the front covers, there are many visual clues to what and where is pictured, and samples taken at random from each volume indicate that a percentage of the prints are captioned on the verso in ink, presumably by the photographer, who unfortunately remains anonymous. In addition, there are also approximately 185 reproductions of early black and white photographs, 35 commercial colour (postcard) photographs and 30 miscellaneous photographs (including a few of people, which may lead to the identity of the photographer).
