Can't remember who is in the photo

and it's been driving me mad all day!

There is a photo I remember from (I think) the early to mid Seventies.

It's a head and shoulders shot of a beautiful black woman in the 'Nefertiti' pose. She has an afro and has a strip of material around her head that makes her hair stand up. It's a great picture. And I think it's monochrome but I might be wrong.

I did think it was Marsha Hunt but can't find it in Google images.

Anyone know who it is?

Good guesses and there's a couple I can google. It was before Grace Jones though.

It's not Mari Evans either
