Heimische Vögel : Zum Nachzeichnen und Ausmalen
A German natural-history picture book of native birds, published by Wigand in 1856 by Hugo Bürkner and Ernst Hasse, meant for children to copy and colour. Its plates pair two small wood-engraved birds on each page with German captions, and the figures are drawn in clear outline with little shading. A designer could take from them simple, readable bird silhouettes and the open, uncluttered page layouts with a single framed image above another.
