We are excited to share a working draft of research by former Conservation Technician Marci Jefcoat titled "American Civil War Revenue Stamps on Photographs"! This working draft focuses on American Civil War Revenue stamps within the brief yet pivotal period 1864-1866, with emphasis on dating and/or estimating initial retail price of cartes de visite based on revenue stamp characteristics. Includes a brief history of revenue stamps, an exploration of cancelation methods from stamps to handwritten markings from the photographer, complete with photographs and analysis of specific examples.
