Cage Transformation Box. British, ca. 1880. Toleware box elaborately finished is shown empty, and the door is closed. Upon reopening the case, a wire birdcage – entirely filling the interior – has appeared. Can also be used to transform articles into the cage or vice versa. Cage includes door to accommodate a small bird. Height 5 ¾". Finish well worn. Regardless, a handsome example of this Victorian prop.
