tazdmb - those look like his wifes ghost signatures (attached wife signed 1919 contract)

Jobo - good points, one counter is people put facsimile writing and signatures on things all the time even in that time period, not an uncommon practice to do that. I would add that I think someone who has spent 20-30 years looking at Joe Jackson autographs would have a better idea of what his signature looks like than an employee at PSA (a company who has authenticated bad autographs in the past so their opinion is not above reproach either)

It is for sure possible one time in his life Jackson was handed a photo and signed it and happened to sign it completely different than he would sign everything else the rest of his life...but I doubt it

I think it is easy to yell fake if you are just doing it to be provocative...but trying to lay out reasons why someone thinks that is not the easy way and just opens them up to be questioned and possibly ridiculed (as has happened in this case)...the real easy way out and take here is someone blindly accepting it I would argue.
