Lost Creepy Arthur PBS Bumper

Could it have been a halloween bumper?

IIRC, PBS has some sort of local content rule, so I would not be surprised if it was a regional thing. I've heard a few PBS stations aired The Big Comfy Couch & there's KIKU from Hawaii which aired various subbed anime on Sunday nights, possibly terrifying a few kids.

Trying to keep this thread active. How can we find the Arthur bumper?

I watched a complination of Arthur funding credits and also looked on the archive of those on a fan wiki. I couldn't find what OP is describing.

However, I did find a similar black BG and glowing text card used for various shows as seen here. company-bumpers.fandom.com/wiki/PBS_Viewers_Like_You_Bumpers

It's the ones under 1989–95. Probably not it though since most of these are yellow fonts. It could be possible this is a very rare variant used in one region like suggested earlier.

Yeah, around days later I started to notice the timeframe of the bumpers and the show's air date. I guess I got too excited when I saw something similar but definitely not the same.
