Le Merveilleux was Lancaster's lowest priced series of cameras for the amateur. The camera itself is a primitive folding view design constructed of polished mahogany with brass trim. A simple meniscus achromatic lens, standard for the Le Merveilleux, was mounted in a brass tube that slides forwards and backwards for focusing.

This example is the tiny ¼-plate model exhibiting an understated yet elegant appearance. Lancaster offered the camera in plate sizes ranging from ¼-plate through 12" x 10".
