Madame Alexander originally produced Cissy dolls in the mid-to-late 1950s. At that time Cissy had a resemblance, in my eyes, to the Miss Revlon or Toni dolls. She was the same height as now, 20-21", with a lady doll figure, and high-heeled feet.
Cissy came back with a makeover and a vengeance in the late 1990s. She was an extreme diva, and her most fervent collectors called themselves "Cissy Swine," as Cissy was a demanding dolly and always needed another outfit or more jewelry. Cissy is still produced, but the changes have turned off many diehard collectors. For one thing, the price has doubled or tripled; Cissy now is around $1000 at retail. New Cissy has bending elbows, but word is the vinyl is not as high quality as the earlier dolls. She also has a different face mold, that can appear "mean" or unhappy. As so often happen with doll lines, Madame Alexander changed the Cissy doll and got rid of lot of the things that drew in previous collectors. Whether this is a good thing or not depends on doll sales in the end, and I don't have those numbers. One more note, Hollywood Cissy also came with an African-American skintone, and black hair in the same style as my doll.
It's amazing what taking photographs can do for your appreciation of a doll. Cissy is on a shelf in my bedroom, so I see her every day, but when I put her in front of the camera, she really came to life.
