There is a great selection of early drawings and photos of the Puuc Maya region (of which the best-known and most extensively restored site is Uxmal) at a site called Architecture, Restoration, and Imaging of the Maya Cities of Uxmal, Kabah, Sayil, and Labná. The site offers both recent images and historical ones. This shot, from 1888-1891, is by Henry N. Sweet, a member of the Edward Herbert Thompson/Peabody Museum expeditions. It shows the structure known at the Codz Poop at Kabah (one of my favorite sites). The image at the top of this page is a detail from this facade, a photo I took in 2007.
