Best thriftscores are always in the back

It's been awhile since i found a treasure to add to my collection of 60's and 70's big eyed art.

One of the joys of thrift shopping is that you never know when or where you might find that perfect piece.
Like all the way in the back of a tiny thrift store, behind a bunch of dusty, uninteresting paintings.
There she was. Sweet big eyed Indian girl.

It's a big piece (18x22"), but that didn't keep me from taking her with me. It may sound strange, but in the store she looked a bit sad. And the moment i brought her in to the house it felt like she started to look a bit happier.

It's one of those pieces that when you end up with it in your home it feels like it was supposed to be there all along. You instantly can't remember how the wall looked like without it there.

I had to take the frame off to be able to see the signature on it, it looks like the title plus initials of the creator. "Hasler Twin B.I.". Does that mean she is part of a two piece series?
