Nice Vintage light up Roanoke VA Garst Bros. Dairy clock
These clocks use to bring $600-$800 but with so many of them in the area (Roanoke VA), most of the main collectors already have one and the price has been dropping over the past 5-6 years. You can pick them up for about $200-$300 and even less from average people that have them in garages and basements. I saw one sell at a yard sale for $50 this past summer (which was a great deal!).
