WWII German Army Sun Helmet with G.I. Annotations

The green wool felt sun helmet is tagged as a size 58. The exterior and the interior show handwritten annotations by American soldiers, most with a name, home town, and state. The exterior shows some soiling from wear. The interior has some separations of the lining around the sweatband. The interior includes the annotation of “Sissons, France, Sept. 25 1945” (probably meant to be “Soissons”) and “Honey This is a German officer hat used in Africa”.
