The combination of the middy blouse, voluminous 1910s hairstyles, and the factory setting strongly points to the late 1910s. This aligns perfectly with the WWI era (1917-1918) when many young women entered industrial work, and matches Esther Burd's age (approx. 18) and residence in the manufacturing hub of the Dayton, Ohio area.

They are dressed in blouses and protective aprons, sorting or assembling small metal parts contained in wooden trays in front of them. The industrial setting features painted brick walls, wooden support pillars, and large windows providing natural light in the background.
