Interesting pic. Thanks for sending the HIN. Model number says it is a Sunsport. We've discovered some interesting models from the early 90's when Supra was just trying to survive as a company after a recession and bankruptcy.
As far as this decal, never seen anything like it. It does seem similar to the Espirit or Impulse graphic font from that same time. The location of it is the only thing that doesn't make sense. It looks like it is right where the trailer guides are which should be where the wave graphic should have been.
I have scoured through my stack of brochures and magazines from this era but I'm not seeing anything that has the Sunsport Spirit.
I'm open to know more if anyone else has an idea, but I'm at a loss. The good news is that this is a composite Sunsport and a good performer.
See link below where we discussed another interesting find and I had some posted pics from brochures.
