The firm, rivals to Tiffany & Co. and Black, Starr & Frost, commissioned designs from Copeland Spode and Thomas Minton Sons, that featured hand-painted details over transfer-printed outlines and often rich gilding. Porcelain by HavilandRoyal Worcester, and Villeroy & Boch also appear with the firm's stamped underglaze marks integrated with the manufacturer's. Davis Collamore was among the first to recognize the beauty and value of American-made cut glass and also offered Rookwood Pottery,[2] for which they were the representatives at the Exposition Universelle, Paris 1889.[3]
