A black-and-white photographic postcard of National Guardsmen with a machine gun mounted on the back of a flat-bed truck on the streets of Tulsa, Oklahoma. Several soldiers are on the back of the truck with the weapon, one standing and one kneeling to the left of the gun and one at gun sight. Several other soldiers march next to the truck, backs to the camera. Other vehicles and soldiers are visible on the street in the background of the image. Written in white at the bottom of the image is [NATIONAL GUARD / MACHINE GUN CREW / DURING TULSA RACE RIOT 6-1-21].
The postcard is unused. The back of the postcard features [POST CARD] at the top in outlined lettering, an AZO stamp mark with triangles at the four corners, and a divided back with a spot for [CORRESPONDENCE] on the left and [ADDRESS] on the right. There are no inscriptions, front or back.
