This was in an envelope in the little typewriter case labeled “Shelton & Kin”.
Winecoff School, Concord, Cabarrus County, North Carolina
I’m not sure of the date without more research but I’m running with this picture being of the graduating class of (ca.) 1939 of Winecoff School (Concord, Cabarrus County, North Carolina). My grandmother, Ella Louise (nee Cline) Anderson, is the 4th person from the left on the first full bottom row. At the time, the school served children from 1st grade to 11th grade when they graduated. No info on the back of the picture.
