By Design takes a stroll through the streets of Adelaide, investigating how the city has changed since the early 20th century. In 1936 photographer Gustav Hermann Baring celebrated the city in his publication Progressive Adelaide: As It Stands Today. This was both a catalogue of commerce and a labour of love. In 2012 photographer Mick Bradley and writer Lance Campbell set out in Baring's footsteps to photograph and write about the changes. Their book City Streets: Progressive Adelaide 75 Years On shows how the buildings and the streetscapes have changed—or not. It is a fascinating journey.
