Smash Bros. WiiU Dollar Easter Egg

I'm not sure it's Sakurai's Signature, actually.


Then again, it could be cursive handwriting being mashed together and hard to actually read.

I'm pretty sure it's his, the first and last names clearly start with "M" and "Sak" respectivly (See close-up attached to reply). And also, what other M.S. name could it be?
