That looks fake. Its colors are so different from what we are used to seeing.
I've been going through an Obama slide show over at
Time, and it struck me that this signature looks like it's done by someone with Parkinson's disease. then I remembered they do that souvenir pen thing, where they draw a fraction of each letter of the signature with a different pen so they can use like 20 pens to sign a bill into law and give them away to VIPs.
Still, it looks funny.
