The mosaic cards offered visual catalogues of the luminaries of a profession or social group in a single photograph. Here the emperor, his wife, and son top a pyramid of statesmen, soldiers, artists, writers, and others affiliated with the imperial court. This image was produced by cutting hundreds of figures photographed by Disdéri away from their backgrounds, mounting the likenesses on a single sheet, photographing that collage, and printing it on 6 x 9 cm cards.
