Have you seen her anywhere?

She is obviously from MET-ART but her name is not Mechelle. I'll see if I can find her.
I looked through all my MET covers back to 1999 including Met-Models and Met-Girls and could not find her, which bugs me because I think I've seen her.
Maybe, she's from RWB Productions? I've just remembered! Do you have anything from them?
