This is a Victorian Cabinet Card - Portrait of a County Durham Family With a Tennis Racket Prop CBC16
The cabinet card was likely taken between 1880 and the early 1900s, with a strong possibility of being from the late 1880s or 1890s due to the peak popularity of cabinet cards and the ornate style of the photographer's imprint.
The women's dresses likely feature a bustle, which was prominent in the 1880s, creating a pronounced projection at the rear of the skirt, although by the 1890s, the bustle had reduced in size or disappeared, leading to a smoother back silhouette.
The fashion reflects the prevailing Victorian emphasis on formality and structured silhouettes for both men and women, transitioning towards the slightly softer, S-bend silhouette of the early Edwardian era for women and continued refinement in men's tailored wear.
