Uncolored litho print. This is an unpublished form of the illustration. The published plate is in portrait aspect rather than landscape as here, and the setting is changed from a tree branch to a cliff top. Close examination seems to indicate that the image of one bird was drawn separately and then partly superimposed on the other; certainly the position of both birds on a single branch in Gould item 2268B is difficult to comprehend. Pencil lines here call for changes to the throat and top of the head of one bird; the changes can be seen in the published plate. Also in pencil: "Turnix = Swift-flying Hemipode / [Piccadilly notes 9:] 799 / [Piccadilly notes] 22/2621 / 5/5/-" (Sotheran's book catalogue reference and price). Previously cited as GS3 or 3GS (and so marked in pencil on reverse). Artist's name(s): Gould, John; Richter, Henry Constantine.
