Levi Walter Yaggy’s Geographical Maps and Charts (1887/93) https://publicdomainreview.org/collection/yaggy-geographical-maps Amazing maps of the cosmos and the Earth including the entire Earth mapped as underground caverns. "Levi Walter Yaggy’s Geographical Study (1887) unpacks like a matryoshka doll. The experience begins with a heavy wood box, outfitted with leather straps and brass clasps, inside of which is a sheaf of complex maps and charts, and a learning guide on how they should be used in the classroom. The maps are each the size of a small rug (ranging between two and four feet) — large enough to lay on the floor and have pupils gather around — and all save one are printed expensively, on thick paper with chromolithography. The exception is a green relief map of the United States, made of plaster and papier-mâché and built directly in the carrying case. It’s the least charming of the suite, though it made Yaggy justifiably proud: most of the mountains he depicts had yet to be measured. The remaining maps, of Earth and its cosmos, are packed in such a way as to avoid being crinkled by the Rocky Mountains." They don't make them like they used to.
