what is this font/closest font; the "tobyMac" part

It's some variant of Futura.

The sharpie "tobyMac" part, not the 'EYE ON IT" part

Ah, sorry.

Seems like a specially created font, so it may be hard to find. So I may have to settle for closest.

Maybe this?

I've seen it in use, by the artist, as an actual typerface. I believe he did a handwriting scan to create it though, so I'll have to use a similar font.
