Original 1944 German Feldpost Letter Sheets Lot of 5 Unused WWII Mailers w/ Calendar

Offered here is a lot of five original unissued German Feldpost letter sheets dating from 1944. These wartime self-mailing forms were intended for use by soldiers and civilians corresponding through the German field postal system and feature an integrated 1944 calendar printed on the inside flap.
Each sheet remains unused and retains its original dry gummed backing, which is still in good condition. The forms display the characteristic textured wartime paper and instructions for sealing. A particularly interesting feature is the printed 1944 calendar, which collectors may appreciate for its historical value. Since the 1944 calendar layout repeats every 28 years, it also corresponds with the upcoming year 2028, making these unusual conversation pieces as well.
