100 years ago...early pix of Dad

I don't know where this came from...just found it recently, but it is a small, 2" by 2" fuzzy photo, and it is the earliest photo of my Dad, Terrence Miller Clark, aged less than one year? If so, the photo is 100 years old, because he was born in January, 1914.
My grandfather, Erle T. Clark, is lounging on the grass in Comanche, Ok., with the baby. It is definitely Erle from his profile, probably smoking a pipe. On the back of the photo, in neat cursive writing, it reads "Erle Clark & Terence," and "You & your dad." I know it is early, because Dad later added another "r" to his name, and was known as "Terry," hence my name.
