A seal can easily be “Photo-shopped” onto an image - especially when the file is saved within an editing program, as the Factcheck images were.
When the paper is flat there’s no way for the unaided eye to tell whether a “seal” was added digitally. It’s when the 3D aspect is shown that you have the potential for problems that would reveal a “Photoshop”. There are 2 images which claim to show the “seal” in visible 3D.
The one I told you about is problematic because the “seal” doesn’t distort with the fold - which is not reproducible in real life and strongly suggests that this seal did not exist on that paper in real life.
The other one is an image looking down the fold that has the “seal” on it. The problem with that one is that there is nothing on that document that identifies it as the same document that has Obama’s name on it. And in fact, there appears to be a line of print missing from what is on the Obama COLB. So at best it is unknown whether that is a photo of the Obama COLB and at worst it appears to definitely NOT be of Obama’s COLB.
So every 3D image showing the “seal” is either problematic or (at best) inconclusive. This is stuff that is on the Factcheck site itself and can be verified using only the naked eye. No computer or image processing at all. No reliance on documents whose provenance is unknown. Just basic observation.
Do you see how you are going to great lengths to find reasons to reject anything that doesn't support your suppositions? Such as focusing on a few photos that lend themselves to misinterpretation while ignoring photos that do not.
This is likely at least one reason why you never feel like you are getting anywhere. Anything you learn that doesn't support your presumptions is rejected, attributed to either conspiracy or corruption or perhaps taken as proof that you are being actively opposed in your efforts rather than that you are simply mistaken.
At this rate, why should anyone take you seriously when you say that if only you were to get this next thus-and-so you'd be satisfied if it wasn't in your favor?
