It says NES.

You have found the secret nintendo wheel mouse optical!

Also, the wheel looks black while mine is kind of grey. Could be the lighting tho. Weird.

Isnt it just a standard ms mouse, with the logo printed above it?

AIDS mouse lol

omg, it's BLACK!

Why's it always gotta be about color?

I actually have one myself

trackballs i us image?

There's a Korean company you can go through to get custom printing on WMOs and other mice. This is probably just a corporate branding by a foreign OEManufacturer for distribution with their hardware.
Since the WMO was so well distributed by OEM, this would make alot of sense.

Where did you find this image?

I put the logo into google image search, and nothing turned up.

This was one of its suggestions:
