Lee and Shepard Advertising Cover

Here is a great advertising cover on which Lee and Shepard advertised Oliver Optic's Magazine. Although the date is not noted anywhere on the envelope, Lee and Shepard was located on Franklin Street from 1874 to 1885. Since Oliver Optic's Magazine was discontinued in 1875, this cover is from 1874 or 1875.
