My mom saved the Barbie Dolls she had when she was a little girl, along with a carrying case and several outfits, and she gave them to Lauryn (to play with, not just to save). Considering these ladies are nearing fifty years old, they look pretty great.
The boys have strict instructions not to touch them; the dolls wouldn't last a day if subjected to their rough housing.
I don't remember actually playing with these dolls, but I do remember using them to my advantage in Jr. High. They were kept in the attic at my grandparents house. I used to ask my Grandma if I could get up in the attic to get the Barbies and show my friends....but I really only wanted up there because my Grandparents bought toilet paper in bulk and kept some up in the attic. (Not sure why they did that...it suddenly strikes me as odd.) I just wanted in the attic to swipe the toilet paper to go TP'ing. That was the worst, if not the only, transgression against my grandparents growing up - and they probably would have just given it to me if I had asked!
I have to tell you that if these are Real Barbies, it will be stamped on their behinds or the back of their heads with the date. If so, they may be worth a mint along with the Barbie case.
You might want to save them for her college tuition.
