Dorothy Sturm’s beautiful watercolors are difficult to distinguish from an actual microphotograph (except perhaps they are clearer and more detailed than a micrograph
, and certainly superior to images from the 1950’s).
Sturm’s watercolour on paper illustrations, drawn directly from Wright-stained smears prepared by [microbiologists], depicted normal, pathological and infectious hematology with a clarity, detail and beauty that photomicrography of the 1950’s simply couldn’t approach. JAMA, in a review of the first edition, even called her work “of exceptional quality.”
 This table showing hematopoiesis (as it was understood in 1956) was the frontispiece of the first edition of Diggs’ The Morphology of Human Blood Cells. Here’s the key to this illustration.
 Cell types found in smears of peripheral blood from normal individuals
 Blood parasites
 Fat cells
