1) when you're sharing imgur images, use "linked BBCode" — it works beatifully on Vogons and gives you proper thumbnails in the post 😀
2) maybe something is written on the backside as well?

Edit:

looks like PC Chips Cheetah v 1.7

The only thing identifying it is a sticker dated July 31, 1995.

That's pretty late for a 486 VLB board, I think. Weren't Pentiums and PCI already out and semi popular? 😕

That sticker could mean anything - for instance the date when it was installed after being for a few years on a shelf, the date when it was sent or returned from repairs, etc. By no means does it have to be the manufacture date.

I think it is a PCCHIPS M912.

Given it is a version 1.7, I would do a thorough check on those cache chips as this revision is rumoured to have fake cache.
