I1978  Underwood’s Inks Quart Master in Cobalt Blue Glass. ca. Late 1890s. Underwood’s Inks is embossed on front of bottle. Measures 3.5 inches diameter at base, height is 9.75 inches. Pour spout molded in the top opening. This would have originally had a cork in the pour opening to preserve the ink. I do not believe there was ever a label on this beautiful bottle. Excellent condition. (1 avail)
