[1] Lumme arrived in Australia in 1881 and set up business in Ashfield, New South Wales, as a photographer.
[2] The photographs were taken in the Central Tablelands of New South Wales, most being of the residents and village of Mandurama as well as Lyndhurst and Carcoar but there are images from as far west as Boorowa and many from unknown areas.
In addition, the images include the residents and areas of Cowra, Boorowa, Burnt Yards, Garland, Gallymont, Neville, Shaw, Blayney and Orange.
The photographs are considered an invaluable resource for seeing Australia as it was in the Victorian and the post-Federation eras.
After their rediscovery, the collection was given to the National Library of Australia, and since then has made a short return to its home of Mandurama, during the town's 125th anniversary celebrations.
