André Adolphe-Eugène Disdéri - Untitled (French Military Heroes and Political Leaders) - 2017.12 - Cleveland Museum of Art

This montage of France’s military and other leaders is a mosaic carte, a form invented by Disdéri, produced by cutting photographs of hundreds of figures away from their backgrounds, mounting the likenesses on a single sheet, photographing that collage, and printing the result on 6 x 9 cm cards. These entertaining images sold well and were effective advertising for the photographer’s prowess.
