Mattel is a well known name for dolls and are all well made. They are a company you can trust for quality and value. SALE PRICED NOW! "Baby Grow Up" has a pull string operated doll that would "grow" from 16 1/2 to 18 inches when the string on her back was pulled. When you pull the string on her back her two-piece torso shrinks and her neck shortens to her "baby" 16 1/2" height. Release the string and she returns to her "toddler" 18" height. This doll DOES work when you pull her string. Hard plastic body. I am not sure if her clothes are original. Her pretty blond hair in in 2 pony tails. What an awesome doll to have for your own. Clothes smudged from age and being out on display. Total price includes shipping cost.
