Mmh,
I looked at their offered Stephen Hawking. We all know, that he haven't been able to sign for many many years.
The signed photo is suposed to be from the early 70s. But look at the electric plugs in the background on that photo. Are they really 50 years old. And the other things in the shelf.
One can date Stephen Hawking photographs fairly accurately by studying his wheelchair and the communication equipment he employed, which was constantly evolving as his condition worsened and technology advanced. This photo I would date to between 1990 and 1992.
