Big O help
 

I want to sell this, and think its a preprint. anyone ever seen this? THANKS. scott

Can you look at it with a loupe? I've noticed that most pre-printed signatures on cards can be detected by looking at it under a loupe and the printed signature will show as dots/pixels like the old TV screens used to when you looked closely (the tri-color pixel/dots). I'm sure there's a technical term for it, but I don't know what it's called.

I used a decent regular glass, and Im prett sure it is a preprint, but hard to tell. Was hoping someone may have one of these, before I sell it too cheap or too much. thanks though for the advice:)

It looks like it was signed with ball point pen; Look on the back and see if you see impressions from the pen point....Also you can look at it under a light moving the photo back and forth and see if it's live ink
