Frankfurt am Main, Heinrich Keller, 1879. Oblong folio (26.9 x 37.0 cm). 93 mounted collotypes (each oblong, ca. 8.5 x 12.5 cm) on larger, printed sheets. Original portfolio of quarter pebbled cloth over plain boards. Printed label mounted on front board.

An exceedingly rare, complete collection of collotype prints after original photographs of price-winning dogs at a dog show in Hannover, Germany. The images are excellent: very natural in detail and contrast, and carefully mounted on printed sheets with additional information, including the dog's name, breed, and owner. The photos were made by the brothers Wunder in Hannover. Plates loose, apparently as issued. Slightly, uniformly age-toned - a bit stronger near the edges; a few creases and an occasional spot, but generally clean. Covers rubbed, especially at corners and spine ends. The paper on which the photographs are mounted is generally age-toned. Some outer margins of plates chipped and slightly brittle, first plate professionally restored. A true rarity; OCLC (WorldCat) reports just two copies in libraries worldwide: one in Zürich (lacking plates 27, 30-34, 37-44, 47-49, 56, 78, 93), and only one complete copy in Williamsburg, VA. Not in any major bibliography.
