Modified Mid-Century Undershirt with RAD Insignia

This post WWII, mid-century white cotton sleeveless athletic undershirt was manufactured by Idreo. The interior collar retains a woven maker label marked "Idreo 5" with a red factory batch stamp "20019" on the reverse. A shield patch displaying the Reichsarbeitsdienst (RAD) spade and wheat motif in black, white, and red is machine-stitched onto the center chest. Added post-era for theatrical or reenactment purposes, the patch creates a military aesthetic on a civilian base garment. Small age spots and minor fabric toning appear around the insignia, but the shirt remains intact throughout. B
