“Decorating a soldier’s grave in one of the Negro sections on Memorial Day [1943],” Arlington Cemetery, Virginia, by Esther Bubley, via Library of Congress Prints and Photographs Division.
The graves of service members were segregated by race until 1948.

What a moving and appropriate picture for the day, which originated with African-American families of Union soldiers.That the women here are decorating in a segregated section — of *Arlington*! — just makes the history stab that much harder.
It shocked me.
Given the date I wonder if this is a new. WWII grave?
It could be, although the grass looks really well established. It also could be the grave of someone who fell in World War I. The women could be widow and daughter.
