This Alien registration Card, issued by the U.S. Department of Justice to Vena Peters Schock of Topeka, KS, was issued during World War I due to Schock's status as a non-naturalized citizen of the United States. During World War I many German Americans were issued similar registration cards that they had to carry at all times. If a non-naturalized German American was stopped without their card, they could face imprisonment until hostilities between Germany and the United States ceased.
