NSDAP membership card - 17 year old Austrian, 1944

NSDAP party membership card, issued to Herbert Lorenzoni, who joined the Nazi party in late April 1944. Lorenzoni joined as a 17 year old, his date of birth being July 31st 1926. He was from the Austrian city of Graz and was given the membership number of 9 849 323. The card has six membership dues payment stamps for 1944 and an embossed NSDAP Ortsgruppe Steiermark certification stamp on it. In excellent condition, interesting card, I haven’t come across documentation for such young NSDAP members before.
