A dramatic cross-section reveals layered mountain ranges and river systems in muted earth tones, with hand-colored green valleys nestled between towering peaks rendered in soft grays and whites. Dense lines of text fill the upper portion in a meticulous cartographic style, creating a scholarly density that grounds this geological study in 19th-century scientific illustration. 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.
