The reverse of a 1945 'Jumbo Post Card' from San Antonio, Texas, combines a description of an aerial view of the historic Alamo with wartime home-front messaging, including the 'Keep 'Em Flying' bomber-crew emblem and a security reminder warning that careless talk or writing could aid the enemy. Such items illustrate how everyday tourism and correspondence were woven into the fabric of wartime civilian life. Project: 218515
