Looks like it, but it looks altered. And it also looks like someone named Ann D something was the original signature and the Stanley in parenthesis was added to make it appear authentic.
one R shows in barack but not the rest of the name.
Also, barak sr did NOT spell his name with a c.
I have seen that Stanley added like that somewhere else.I think in the passport documents.
Didn’t the mother’s sig differ from the first fake and this fake?
