This photo was among those belonging to Laurie Baker. It's a Kodak photo postcard from Vice Regal Studios at Grafton, NSW. Apparently Kodak postcards didn't appear in Australia until about 1907. Laurie's youngest sister Joyce was born in 1909 which would match the age of the photo but I can't see any resemblance to Joyce in her later photos. None of the other siblings' dates of birth fit with the postcard style photo. The photo could be of a relative or friend but has been tagged "Baker family" for the moment. More research is needed.
