These images come from sepia toned postcards published approximately between 1910-1920 by an unknown photographer. All of this series of postcards are from caves in the South-West of Western Australia.
The postcards were supplied for scanning courtesy of Mike Kouwen ph (618) 9384 4981 (h) 9327 0770 (w). Mike is keen to acquire additional cards or details to assist in his research.
Postcards have significant historical and collector interest and value. So please dispose/sell them thoughtfully if they are not required.
