A Preliminary Study of the Coleoptera Attacked White Fir (Abies Concolor)
A 1930 forestry study by William D. Bedard, published in the United States for foresters and entomologists, examining beetles that attack white fir trees in New York. The pictures are small black corner marks on blank pages, apparently abstract tick-like shapes with no drawn subjects, so a designer might use them as minimal framing or bracket motifs.
