These dolls were introduced by Madame Alexander in the 20th century to represent characters of the four march girls -Jo, Meg, Beth, Amy, their mother- Marmee and Laurie – the boy next door, from the book by Louisa May Alcott. Earlier, they were produced with jointed knees and elbows. However current versions have joints at the neck, shoulders and hips. They are made of hard plastic and synthetic hair glued on the head. They have sleepy eyes with molded lashes and about "12" inches tall. Their outfits can be known by the neck tag since they changed several times during the years.
