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 1/4 plate model exhibiting an understated yet
elegant appearance. Lancaster offered the camera in plate sizes
ranging from 1/4 through 12" x 10" as noted in a reference entitled
"How To Be A Successful Amateur Photographer".
