8.5x10.75x3" deep. Reverse includes patent text and 1899 date. The clock face is a tanned paper label under glass 2.75" dia. while the actual wind-up mechanism is held in 4.5" dia. round case on reverse. Clock winds but does not keep time. While this piece is not particularly rare, this example retains nearly 70% of it's original finish, correct clock, and its original hardware on the rear of the clock. Fine. Don & Mildred Wright Collection.
