The story

Trouvelot made some fifteen thousand drawings at the eyepiece, and in 1882 Charles Scribner's Sons published fifteen of them as chromolithographs at a scale nobody has attempted since. Photography could already record where things were; it could not yet record how they looked. So for one narrow decade the most accurate images of the sky were made by a man drawing what he saw, in pastel, by lamplight — and they remain the most beautiful. Trouvelot is otherwise remembered for accidentally releasing the gypsy moth into North America, which is a hard thing to have on the same résumé.

About this reproduction

A faithful reproduction of a public-domain map held by Library of Congress / Wikimedia Commons — the work is centuries out of copyright.
Printed to order on archival cotton-rag or textured laid stock, pigment inks rated 100+ years.
Color-managed to the source scan; we correct nothing and invent nothing.
Ships in 5–10 business days, rolled in a heavy-wall tube (framed and linen-backed pieces ship flat-packed).
If it arrives less than perfect, we reprint or refund — your choice.

Why our maps cost more than a poster: we print from the highest-resolution scans in existence, at sizes where the engraving itself becomes visible — the sea monsters, the tiny place-names, the burin lines — on stock made to outlive its owner.
