ghost photo sold ebay

Tony writes, "this is a real photo showing a young child playing on the floor. Around her you can see an old stick and ball wicker rocking chair - another fancy chair - a very decorated rug on the floor - and what looks like a GHOST right next to the baby. I suppose some could say it was a "trick" of the camera, but I'm not sure how they would have accomplished that back in the early 1900's?!! The ghostly image looks like another small child - sitting on the floor next to the live child. See for yourself. The "evidence" seems to speak for itself."
