Anotations

Scope note:

Works of art, typically on a paper or vellum support, to which designs are applied using crayons made of ground pigment held together with a binder, typically oil or water and gum. Works in this medium are sometimes classified as drawings, and sometimes as paintings, typically based on the local curatorial department responsible for the work or on the material of the support (pastels on paper may be classified as drawings, while pastels on vellum may be classified as paintings).
