Is this a font?

I seriously doubt it since none of the letters match (if it was a font both N's would probably look the same).

I think it can be done by typing something close like franklin condensed and using a special effect. In illustrator you might add anchor points then mess with some of the options under effects, distort and transform, pucker and bloat. MAYBE... worth a try.
