Baby Ghost Over Grave Famous

This famous ghost picture has a baby manifesting over a grave. Here's the picture and story of what happened:

Around 1946, this ghost photo was taken in Queensland, Australia by Mrs. Andrews who was taking a picture of her 17 year old daughter's grave. Mrs. Andrews was surprised by the ghostly image of a baby looking at her when the picture was developed.

Mrs. Andrews maintains that no children were in the area, so a double exposure was impossible, and that she did not recognize the baby at all.

Others who have visited the grave site have found the graves of two baby girls nearby. Could this baby over the grave be one of them?
