I never even saw this was here, before now. That is very strange. I just saw this post for the first time.
I think that is a character doll, like a celebrity doll, but I am not sure of whom. She could be a county singer.
I think I have seen her on the Gloria furniture box. How sturdy is she? She looks to be good quality -- not cheap like the 1970s Maddie Mods I had thought she would resemble.
Congratulations on your find!
I tried BETTY TONG.
My Russian community has 20+ pages in Betty topic,here's what I found beside the pics of dolls:
"Gloria is a barbie clone that has been produced by decades in china, and has been distribuited around the world. She has a beautiful face, with a very sweet expression and rooted lashes. She also has a TNT waist, as MOD era barbie dolls'. Gloria has a complete line of furniture and accesories which I love, 'cause it's very realistic and detailed. Here's Gloria at her "Happy Hour" bar playset"
that's copied from Flickr by one of participants....
They say that this doll was known as Betty in Europe. And they say it's extremely hard to find this doll in general, but sometimes it comes in a heap of Barbie clones and may cost very little.
You're welcome! :)
