Found at an antique shop, spent $5 simply because I live in San Antonio, and USAA is a mile up the road from where I work. I intended to look at the pictures, skim and move on. Instead I read cover to cover.
This snapshot in time (1970) provided an well-delivered history of a business and how they responded to the needs and changes in their environment. The short biographies of organizational leaders were interesting, giving snapshots of history specific to those military leaders that ran the organization. The parallel history of San Antonio and its growth and world-wide influence via a single company was interesting as well.
The board of USAA is a who's who of Military Leaders. So many things in my adopted home town are named after board members, such as Brooke Army Medical Center, George Beach Pavilion, Lackland Air Force Base, and more.
Outstanding, and unknown to me, USAA was promoting females in high responsibility and leadership positions, very early in their organization, and well before the push for equality.
