Ghost Baby in Cemetery

This photo was taken by Mrs. Andrews in Queensland, Australia as she visits her daughter, named Joyce, who died at 17. She's all alone upon visiting her daughter in the cemetery and didn't notice any unusual in taking this picture. Surprisingly, an image of a baby showed up sitting in her daughter's grave.

Mrs. Andrews stated she never recognized this child before. Do you think it's real or fake? Double Exposure? You decide..... This photo was taken in around 1946 or 1947. In 1990's, Paranormal Researcher went in the cemetery and stated there was grave of two children besides Joyce's grave.
