Ghost Hand on TV (1968)

This image is claimed to be cropped from a larger picture (which I've never seen), and is claimed to display a hand appearing on the screen of a TV that is unplugged. The picture is stated to have been taken on December 24, 1968. This copy of the image comes from the Ghost Research website [Link Here].

The earliest I've traced the image is to an article written by Brad Steiger for a 1975 issue of Occult magazine:

Note that the picture in the magazine is cropped down to a smaller image than the copy at the top, and isn't as tight on the hand's details... which implies that the copy currently floating on the internet must have come from a different source than the Occult magazine article. Maybe someday I'll find it.
