>>9230357The first true Babs Star Trek set was this one right here. Despite being the oldest, it's the easiest to find. Go to any antique store in America and you're GUARANTEED to find this set wherever there's someone selling Barbie collector dolls.
In the 90's, collectors bought this set in droves, thinking it would be "worth something someday." Well, it's worth about $30 at most, seeing as how everyone kept their ST Babs sets MIB, so there's a glut of them everywhere.
