A hand-colored cartographic map of Michigan displays the state's geological formations through layered regions of pink, blue, yellow, and green, bordered by a decorative frame with a legend and detailed topographical markings. The composition balances scientific precision with warm, aged paper tones, creating an intricate portrait of 19th-century geological understanding rendered in the careful linework of vintage surveying craft. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
