I know that the signatures of many people change as they get older, but that Obama signature on the Selective Service form, in my opinion, is not even close to Obama's signature today.
It is so neat and clearly written that it looks like a woman signed it.
(Please, no jokes that Obama is a woman in a man's body, so he could have signed it if it is indeed the handwriting of a woman.)
It is odd. I don’t know anything about handwriting analysis, but I’m lefthanded so one thing stands out for me. It looks like a righthanded person slowly and carefully filled out and signed the form lefthanded.
