Great Great Gran Ghost Picture

Darren sent us this old ghost picture. Can you see the image of his great, great grandma (hint: look closely)?

"This pic was taken around 1973, using 35mm camera (Kodak film). This was taken of my father and baby brother. The pics on top of the TV are of me and my other brother. The one in the (turned off) TV is said to be of my great, great grand mother."
