"Cartoons of red arteries and blue veins illustrate the principles of cardiovascular medicine. These illustrations appeared on the back covers of The Heart Bulletin. The figures underwent a transition over the years, as the artist [Joseph Schwarting] refined his ideas about illustrating medical quotes.
