Dartboard. 20th century. Berg Specialties Co., Troy, NY. This graphically pleasing dartboard measures 30" across the diagonal. It is heavily constructed of 1 3/4" thick laminated pine. The taget area is outlined with strips of tin, which protrude from the board's surface. The robin's egg blue color sets this piece apart from similar examples. The dartboard is doubled sided with the other side bearing the scars of many a dart.
