Juan Gris included artists’ papers, wallpaper, pages from a book, and a tobacco wrapper in his collage, Book and Glass. The checked areas were created by drawing on large pieces of blue laid paper. (Laid paper is characterized by a series of lines known as chain and laid lines that are formed during the papermaking process.) The prominent texture of this artist’s paper caught and held the particulate matter of Gris’s wax crayon, charcoal, and Conté crayon. The paper was originally light blue, similar in color to the wax crayon that Gris used to outline the collage forms both before and after he cut them. Gris also used tracing paper to capture the transparency of the glass bottle at upper right. (FIG. 1) Other types of paper incorporate the real world into the artwork: for example, the book page from volume four of the Fantômas fictional crime series and the small brown tobacco wrapper. The cut paper fragments were pasted onto a larger piece of newspaper that Gris mounted onto the canvas. Gris partially tore the newspaper underlayer at the top, which allows the weave of the fabric to become part of the final work (FIG. 2).
