Introduced in the early 1860s, the cabinet-card format featured a 4 x 5-1/2 inch print on a 4-1/4 x 6-1/2 inch mount. It was used primarily for studio portraiture, although views can occasionally be found. Prints mounted in this format were made on albumen paper, collodion-chloride printing-out paper, developed-out silver bromide gelatin paper, and gelatin chloride printing-out paper. Along with the carte de visite, cabinet cards were very popular until the end of the century, often sharing space in the family album. 
The cabinet card, a popular format for nineteenth-century photographs, is a photograph mounted on heavy card stock and measures approximately 6-1/2 x 4-1/4 inches. Cabinet cards are usually studio portraits, and cabinet cards of celebrities, a favorite subject, were widely collected in the last quarter of the nineteenth century. The format was introduced in 1866 and soon surpassed the smaller carte-de-visite format in popularity. Cabinet cards lost much of their popularity after 1900 and largely disappeared by the end of World War I.
