This checklist provides collectors with basic information about postage stamps listed with major numbers in the Scott Standard Postage Stamp Catalogue. The country name appears at the top of each page, and each row provides the issue date or year, the Scott number, a description and four check boxes. The first two boxes are labeled at the top of the page as unused and used. The other two boxes are for collectors to label for other collectible options that can be written in, such as never-hinged or on cover.
