It's rare to see step-by-step sequences for illustrations done over a century ago.
British illustrator Louise Wright (born 1863) creates a fashion plate with two female figures, and the process was captured by Percy Bradshaw in a book called The Art of the Illustrator.
Stage 1: "The figures are lightly touched in with pencil on Roberson’s Fashion Board, B surface (extra smooth), the board measuring 14 inches wide by 21 inches high. The design of the costumes is original, and was suggested by certain characteristic details which were in fashion at the time when Miss Wright commenced the drawing."
Stage 2: "Brush work is commenced, Lamp Black and Sables of various sizes from No. 0 to No. 5 being used. Faint washes of tone are introduced into the face seen in profile, for instance around the eyes, nose and chin, while in the other face light washes can be seen across the forehead, down the nose, mouth and shadow side of the face, beneath the chin, and on the neck of the front view."
Stage 3: "The modeling of the faces is carried considerably further, by stippling up the light tones previously introduced. Dead white is still left over the major portion of the heads, but the strengthening of tone which would be noted in the reproduction is accomplished by a delicate cross-hatching with the point of the brush used comparatively dry. This cross-hatching needs very dexterous manipulation, and wherever it is possible to obtain the effect by fresh washes it is preferable."
Stage 5: "The drapery of the sleeve has also been emphasized by outlining each of the shadows with this opaque white, a wash has been carried over the edge of the sleeve to form a frill, and further broad touches of white added to give transparency to the material. A bunch of flowers has been broadly indicated, chiefly with a wash of tone, the petals of the white rose being indicated with the opaque white, the dark flower with a wash of half tone, the shadows being filled in with black. The high lights on the waist-band have also been emphasized with the Blanc d’Argent and the outline of the band defined in the same way."
Stage 6: "The hair has been slightly strengthened in color, the outline of the face altered by introducing a slightly fuller chin, and rather more prominence and fullness in the lips, which formerly suggested a rather simpering mouth. These alterations have been made with Chinese White. The eye and eyebrow have been introduced more heavily, the lips strengthened in color, the line at the back of the neck more definitely drawn."

is a fantasy novel written by Charles Saunders, an expert in African folklore. I wanted Imaro to be a convincing warrior hero, so I located a tall, built model named Darrell, who was in training to play for the L.A. Lakers. That’s Mount Kenya in the distance.
