Genuine vintage Warner Bros. Store item in original box.
14" round x 4 1/2" thick. Florescent backlight works great, but does take 15-30 sec to warm up. As is typical with vintage lamps, this emits a slight buzz after operating for a while. Backlight is turned on/off via switch built into the electric cable. Clock function itself (time) is battery powered and does not require the clock to be plugged into the wall.
