Was it the one in a bumper (We will return.../Now back to...)? If so, I can go try to pull screenshots from my source if I still have it. They might even be slightly higher quality since they're from before a few levels of processing. I think the bumpers came from a 2-hour section of a summer 1986 Saturday morning recorded on VHS and ripped to digital, then posted. Decent quality, actually.

I'm making myself a note to check when I get home.
