Two different colors of ink.
That image you have has been altered.
I have you seen one where the ink is the same color?
There are two colors of ink in the pic SunkenCiv posted.
Plus there’s the ‘DA’ appended to ‘Moore’, exactly how it appeared on Deborah Gibson’s 1999 divorce decree, when Judge Moore’s secretary Delbra Adams initialed the signature stamp that she used on the papers.
Gibson screwed up and included the DA when she copied Moore’s signature from her divorce papers onto her yearbook. That’s why the forgery is obvious.
