Picture on the left is a detail of a photo taken by S. C. Walker in 1877, and reused by James M. Hutchings in his In the Heart of the Sierras (1886). See also a high-resolution version from the Yosemite Nature Notes (1977). Walker also took a photo of Anderson at Dome's other overhanging rock, with Tenaya Canyon in the background.
