This booklet is good for copying practice. All of the lines are clear, but deterioration marks transferred on some sheets. Figurative drawing is best represented, but there is also some architecture, flowers, horses, landscape, and two drapery studies. The text is minimal, but it provides the date, location and materials used for each sheet.
If you want a more beautiful book, Clayton's "LdV: A Singular Vision". It has many of the same drawings (and many more) cleaned up in full color (lines lighter, but still clear). Marani's "LdV: The Complete Paintings" also has clean reproductions of many of these drawings (usually smaller) and excellent reproductions of the paintings.
