Please help identify brown-eyed barbie

She has brown eyes and rooted eyelashes with the black line above her eyes. No twistable waist but she does have bendable knees. She has holes in her feet which are slightly pointed - not flat like Skipper but not made for high heels like some Barbies. Her blond hair is up in a fancy ponytail. I have looked all over the net and cannot find a match! Thanks for any help. Oh, the copyright is 1966, then it also says 1967 and Japan.

You have a Vintage Francie Doll. I'm pretty sure she is Francie with Growin' Pretty Hair (1970 - 1973), I can't tell 100% from the photo - but she was the only Francie with a bun & the body markings are correct. If she is a Francie with Growin' Pretty Hair, her bun will include a retractable pony-tail. I don't have it on the site yet, but here are the current listings on eBay.
