This collection consists of one board, titled The Barritt-Serviss Star and Planet Finder, with a volvelle at its center, published by Leon Barritt and Garrett Putnam Serviss in 1906. The subtitle reads "The Heavens Without a Telescope. The Only Practical Combination Star, Planet, and Sun and Moon Map." Instructions for use are included on the board, which purports to show the ecliptic ("the apparent annual path of the sun"), the path of the planets, and the view of the stars at a given date and time. The constellations of the Zodiac are also included on the map. The item specifies that the map is representative of the Northern Hemisphere.
