A COOL Old Picture

This is a picture of my Grandma Lucy. She was my Mother's Mother. The 2 little boys are her brothers. The little one in the chair died shortly after that I think. I can't quite remember the story.
I thought it was a cool old picture. They grew up in New Mexico and the older boy is holding a old gun of some type.
My Aunt actually has the original picture and I would LOVE to get my hands on that :)
