Vanishing Alarm Clock

A ringing alarm clock covered with a cloth and lifted from a tray vanishes in mid-air. Similar to Marshall models (perhaps a refurbished version of his?), we can't say for certain who made this clock. It mimicks the clocks of the well-known company, The New Haven Clock Co., and features gold brocade detailing over a black velvet surface. Clock face within cloth shows wear from use, some areas of velvet top a bit loose, else very good condition.
