US USN Navy Armored Cruiser Pennsylvania Stereograph Card

This stereograph card features the US Navy Armored Cruiser Pennsylvania, an early 20th-century warship that served in the United States Navy. Commissioned in 1905, the Pennsylvania was renowned for its significant armor protection and armament, representing advances in American naval architecture during this period. Stereograph cards, such as this example, were produced by photographic studios to present three-dimensional views when viewed through a stereoscope, offering detailed visual records of historic subjects. The photograph captures the cruiser at sea, highlighting its armored hull, gun turrets, and superstructure. Measuring the standard stereograph size, the card includes printed captions identifying the subject. Items such as this were commonly collected as souvenirs or educational tools, providing insight into naval history and ship design of the era. This card is a period original, principally valued by collectors and historians for its documentation of United States maritime and military heritage.
