It’s easy to overlook the Walter Foster series of art instruction books. They showed up everywhere, and a lot of them were pretty hokey and formulaic.
But there were some gems among them. For example: "Animation" (#26) and “How to Animate Film Cartoons” (#190) by Disney veteran Preston Blair, who gave millions of budding animators the basics of walk cycles, squash and stretch, and overlapping action. As a kid I was spellbound by the series of drawings of the dancing alligator from Fantasia.
Other recommended titles:
“Frederick Waugh’s Paintings of the Sea” (#153) was recently mentioned by Armand Cabrera on his blog. It is a gallery of the great seascape painter.
“How to Paint from Your Color Slides” (#64) had a fine ship painting by Carl Evers, along with the sketches that led up to it.
“Perspective Drawing” by Ernest Norling (#29). The one I learned from as a kid. Very clear introduction to one-, two-, and three point perspective.
“Heads & Figures in Charcoal” by Charles LaSalle (#51). LaSalle was a magazine illustrator who studied under Harvey Dunn.
“Figures in Action” (#191) and “Heads/2” (#197) by Andrew Loomis. Many of the best plates from his hard-to-find books.
