This United States Banknote Corporation Color Sample Booklet features a collection of colorful notes and scripophily. With its unique design and historic value, this item is a must-have for collectors of all levels. I do not know what time period this is from exactly. Pictures show only a few of the color samples. Small (7.25″ x 3 75″) blue book containing 27 pages of available ink colors for intaglio printing of stocks and bonds. Each page features ornate engine work in various colors (color name is printed at bottom) and an image of a woman holding an orb in black. All pages are intaglio printed. This is a very scarce book, as these samples were created for distribution only to USBC customers.
