If by graphics card you mean 3D hardware acceleration, then it was a Canopus Pure 3D. It was equivalent to the first Voodoo add-in card but IIRC it had 6 MB of RAM instead of 4. It wasn't a standalone card so it had a VGA passthrough from your 2D card when it wasn't active.
As for 2D cards, idk. Unless it was pro reference grade like Matrox I don't remember EGA and CGA cards being branded.
