Oklahoma National Guard Utilities Employee Photo Badge

Ca. 1950s photo employee badge from Camp Gruber, Oklahoma (U.S. National Guard training site). Single print halftone photograph with green perimeter fashioned into a button badge, 2.25." Very Good condition, minor scuffing and residue on the back. Utilities worker, no. 23456 (or so it says). Neat transitional photo badge from the waning years of their popularity.
