Measures 21"x16". Clock does work and keeps good time and thermometer also works and seems to be decently accurate. Don't see these a lot so don't miss out on this great original piece. Cord looks to have been changed at some point. Has a few scuffs scraps and scratches but overall in good shape no cracks. Starts at no reserve! Pics are description so look good before bidding.
