A doll from like the 1960/1970s?

Okay so theres this doll my mom had when she was a kid, it had this weird thing where you twist a nob on its neck and the head/face would change from like having Chicken pox, to sleeping to being a awake. It was called something like 'Head a get better'? Please help, I could also really use the link to a site that sells them or has pictures. It would mean a lot to my mom if I could find it.
