Various drawings, Charles Dana Gibson
From the Toronto Public Library.
Gibson was one of the great masters of pen and ink and a major early figure in “Golden Age” illustration.
Look at the head of the “Gibson Girl” the center, and the variety of lines, from the short, fine pen strokes around the eyes and nose, to the fluid, calligraphic curves at the top of the hair (which I assume are done with a brush). Wonderful.
