In researching Mattel dolls for Volume II of Steffie: Out of the Box, I came across this line of dolls, Family Corners, created by Mattel in the late 1990s. They are 6" tall with articulated arms and legs, and use miniature sculpts. I think Lacey (shown here) and Melody (coming soon) look a little like a small Bob Mackie or possibly Steffie face.
Each doll includes a cardboard doll house and extra outfit. Interestingly, the dolls are designed with different hair and skin tones, and have boy dolls that can be mixed and matched together anyway you like.
I think they are awfully cute. You can see a few more photos of Lacey on Flickr.
