From the Illustrators Division
I found some nice clean scans of an 1866 tome filled with illustrations by 19th century French artist Jean-Frédéric Waldeck.
I believe these are lithographs, which is a brilliant solution for mass producing art before their was photography and scanners. The Met has a nice breakdown on their website of how this was done here: LINK
In my mid twenties my wife bought me a year pass to the Dallas Museum of Art and a few days a week I would go there on my lunch break and draw artifacts in my sketchbook.
I loved doing that so much that this kind of illustration always makes me stop and daydream about what it would've been like to travel to the jungles of central america and just fill sketchbooks with artifact and architecture drawings like these.
You can see more of Waldeck's illustrations from "Palenqué et autres ruines de l'ancienne civilisation du Mexique" here: LINK
