(4) Vintage postcards depicting Adolph Hitler's armored car (Krom-A-Tone) For Sale

(4) Vintage postcards depicting Adolph Hitler's armored car in good condition. These four 5.5"x 3.5" b&w postcards have never been used but do show some minor shelf wear (light edge wear/fading/etc). One card has no image, it just shows the armored car specs. Cards are Krom-A-Tone by Graphic Arts Co. Shipping is free, but cards will be shipped as stamp mail so tracking is not included (unless requested-for an upcharge).
