Was Disco alive in 1989? Please take a look...

Hello all, new/old member here. Couldn't remember past email so it's all new now! Yippee!

Help please, I cannot ID this piece. The paint ribbons are on the backside of glass. It's signed and dated (1989) and I swear it says Tamara, Tamasa (maybe)...Mixed media, line drawing? Whatever it is if it's familiar to you don't be shy, please let me know. I've searched with no luck and can only find one Tamara (de Lampicka) and this isn't she (her?)...

Thanks in advance, Rich
