This pair of gilt framed and matted Cacatua tritons, aka the Triton Cockatoos [Pl. 44 & 45] (which come w/ their original article in a plastic pouch affixed to 1 framed print’s backing) are hand-colored lithos from "THE BIRDS OF NEW GUINEA AND THE ADJACENT PAPUAN ISLANDS, INCLUDING MANY NEW SPECIES RECENTLY DISCOVERED IN AUSTRALIA BY JOHN GOULD, F.R.S. COMPLETED AFTER THE AUTHOR'S DEATH BY R. BOWDLER SHARPE, F.L.S. &c., Z00LOGICAL DEPARTMENT, BRITISH MUSEUM." The pair make a stunning addition to any collection and indeed are in the collection of the Holding Institution: Smithsonian Libraries and Archives and are Sponsored by Biodiversity Heritage Library. The framed litho prints offered are beautifully framed with maximum attention to detail due to their hand-coloring which adds a unique and vibrant touch to the images. These prints not only captivate with their aesthetic appeal (marbleized and gilt framing tape) but also function as precious private collectible historical documentation of various bird species. Providing a window into the natural world of more than a century ago, these framed bird prints stand as a valuable treasure, making them a source of pride for art and nature enthusiasts alike.
