There are many manuals drawing with different methods to initiate us refine our technique and representation. One of the first thing I remember are the booklets drawing painter Joan Miró Ferrer.

William Andrew Loomis was an illustrator of the first half of the twentieth century, in addition to his graphic work, He left a series of books to learn to draw. The practical approach of these manuals along with the gradual difficulty of the exercises are two characteristics that make them especially useful for beginners in the drawing with pencil.
