Paphiopedilum sanderianum, photograph of color plate from Reichenbachia, vol. 1, plate 3 (1888), made in April 1974, roll 197404 slide 10. This is a slide from a project by Lambert Day to photograph all of the old color plates of orchids, offering them for sale in sets, but the slides were on poor quality film stock and have all faded badly. However, the same plates, or almost all of them, are now available as digitized images from the original publications held by major archives and libraries around the world.
