The product is a Civil War CDV featuring Captain William I. Reisinger of the 11th Pennsylvania Cavalry. This original photograph, one of the clearest I've ever seen, created in the United States during the Civil War era, captures a piece of military history from a pivotal time in American history. It serves as a tangible reminder of the conflict and offers a glimpse into the life of a Union officer during this turbulent period. This CDV would be a valuable addition to any collection focused on militaria and Civil War memorabilia.
