(Draper, Utah, US)

#1- Barbie has a lever on her back, blue eyes, holes in her feet
#2- Has bangs, blue eyes and makeup and pink lips.
#3- Dark haired bob, plastic slats in feet
#4- Dark curly shag hair, arms seem to move, holes in feet
Thanks you for any help!

I believe they are:
#1 - Free Moving Barbie - 1975
#2 - Sweet Sixteen Barbie - 1974-75 (Barbie's 16th anniversary)
#3 - I think is Marie Osmond
#4 - Walk Lively Miss America (with Steffie face)
