This is a picture of my father and his sister Beulah. The estimated date is 1911 or 1912.
The picture was probably taken either at Trenton or Chillicothe, Grundy County, Missouri. The family lived in the Laredo area.
Drag the small black-bordered rectangle (inside the small image on the left) in order to see the zoom-effect on the right.1
Use the zoom-effect to focus on Beulah's wrist. It appears she has some kind of dangle bracelet. Notice her shoes are "Mary Janes" or something close to it.
My dad looks like his belt needs tightening. And surprise -- he was had light brown or almost blonde hair. As a young man he had a thick head of black hair but he became bald like his father.
