Eighty Three People? is a collection of drawings by Andrew Rottner.
These images were generally stacked and bundled with twine so that only the top image was visible at any one time.

These bundles were shown in several exhibitions in the Bay Area in 2006 and 2007.

This new edition by Super Classy Publishing makes it much easier to see more than one image. Look for Vol: 2 coming soon.
