Stussy Muddy Fox - is this a thing?

I picked this frame up for free and was surprised to see Stussy on the head tube.

Does anyone know anything about the origins on this frame, as I can't find similar examples from searching Google?

Sticker?

That’s a much earlier frame and headset than those decals.

Yeah right?! I have a feeling that this is a 87 courier. It had old dia comp cantilever brakes on it. Weird.
