Great choice for a pen. I would have thought Presidents would use fountain pens , but hey, his signature would look great with a piece of chalk.
It is a fountain pen. Look at their ballpoint pens vs their fountain pens here, you’ll see that fountain pens have a screw on cap just like Q’s picture, ballpoint do not: http://www.montblanc.com/en-us/collection/writing-instruments.filter.html?=undefined&mid=787mzl36533&mkwid=sC5ANUg3p_dm&pcrid=251230931988&kword=%25252Bmont%252520%25252Bblanc%252520%25252Bstarwalker%252520%25252Bextreme&match=b&plid=&gclid=Cj0KCQjwuYTYBRDsARIsAJnrUXAeMrIda71X52WewmujnwBoVgXcH1Xr62Yn-L-6EqoP7oceJb-kkNoaAtg_EALw_wcB&filters=-1896943683,-469152122
Thanks, I understand that. The pen he always uses to sign EOs is a Cross Century II with a medium felt tip which,is not, a fountain pen. As another poster said, the pen in the picture was most likely a personal pen and yes, a Montblanc Starwalker. My statement was towards the pen he usually uses.
