Sub-subseries I.B.1. Oversize Illustrations (A-M), 1899-1940

Drawings and other illustrations larger than letter-size are organized separately in legal or oversize boxes. Many of the oversize items consist of multiple drawings attached to cardboard backing. Individual drawings may or may not be labeled. Some drawings are separated from their cardboard backing or missing entirely. It appears that many of the oversized pieces were "figures" or "plates" created for publications such as USDA Farmers' Bulletins or leaflets. Other materials include report jackets, drawings, and photographs from the Bureau of Animal Industry editorial office. There are also oversized charts and posters (both numbered and unnumbered) that may have been used for presentations. The oversize materials are grouped first by box size and then in alphabetical order by parasite name within each box.
