Two Gibson Girl–era bathing beauties in vivid red-and-black striped costumes hold open a massive illustrated clamshell — and inside hides an accordion strip of 24 miniature photographic views of Madison, Indiana, patented 1907 (No. 858313) and illustrated by the artist Grace Harby, whose name appears in the lower right corner of this wonderfully chromolithographed cover. Madison, a river town on the Ohio known for its exceptionally intact antebellum architecture, is documented here at the turn of the century through scenes including the "Odd Fellows' Fountain," "The Eggleston School," "Hanging Rock in Winter," and aerial and street views of the town — an irreplaceable visual record of a small American city before the automobile age reshaped it. The back is formatted as a standard postcard with domestic one-cent and foreign two-cent postage boxes and the "M___" salutation line, catalogued as No. 483; it was never mailed. The chromolithographed cover retains strong color with only minor edge wear, and the accordion interior strip is complete and legible throughout.
