Vintage Barbie Francie Doll? Please Help Me To ID Her

[lowbow2004]

Hi there. I have this Barbie doll I believe is Francie that's in need of identification. Back marked 10 on buttocks with the other side marked 1966 Mattel made in Japan. Click knees and possible hair cut?

Any additional information would be greatly appreciated and thanks for looking.

It's not Francie. It's a TNT Barbie with a bad haircut. She dates to 1967-68.

@lowbow2004  @kathiec   Since she has centered eyes and that unrooted spot at the hairline, she's the 1971 TNT (Twist 'n Turn), also called Marlo flip by collectors.
