This is a vintage classroom-style pull-down wall map of Michigan, identified as Map No. PS 121, published by A.J. Nystrom and Co. of Chicago. The map provides a detailed physical relief view of the state, color-coded to indicate land elevations from less than 1,000 feet to over 1,800 feet above sea level. It features comprehensive geographical data including county boundaries, state and international borders, and a detailed transportation network showing Interstate and main highways. The layout includes a large inset map of the Detroit Metropolitan Area with a scale of 2 miles to the inch, alongside a comprehensive city and county index with grid coordinates. Three thematic inset maps at the bottom illustrate Average Annual Rainfall in Inches, Density of Population per Square Mile by Counties, and Land Use and Mineral Resources. The map is mounted on a spring-loaded mechanical roller housed in a painted metal casing, with a wooden dowel at the bottom edge for weighted stability. Printed markings at the bottom center include the publisher credit and the map number. A paper label on the wooden roller also identifies the map as Michigan Physical No. PS 121. Casing width: approximately 55 inches Map width: approximately 51 inches. The map is in fair-good condition with evidence of age and classroom use. There is general yellowing of the paper/linen substrate and minor edge wear with occasional creasing. Moisture damage across the bottom as pictured. The metal housing and spring-roller mechanism shows some surface wear, mechanical components are intact and in working order.
