The most famous personalized pen

It is indeed the most famous personalized pen. It is Barack Obama's and is personalized with his own signature.

Can you identify the pen? My first thought was Mont-Blanc but at second glance it does not look like it. And it would surprise me if the President of the USA signed all of the official papers using a german pen with a french name...but who knows!

Thanks to this blog for the image and idea
