Like many other nonprofits, the Esopus Foundation Ltd. was adversely affected by the 2008 financial crisis. I decided to cut production costs for our spring 2009 issue, Esopus 12, by printing the issue using only black ink. In my editor’s note for that issue, I cited a 1987 collaboration between the legendary neurologist Oliver Sacks (1933–2015) and his patient “Mr. I,” an artist who suffered from cerebral achromatopsia (total color blindness). For this collaboration, the artist painted various pieces of plastic fruit in shades of gray to approximate his perception, which Sacks then combined with colored fruit for a series of images published in his 1995 book An Anthropologist on Mars. Sacks was kind enough to allow us to reproduce two of these images on postcards that we inserted into every copy of the (otherwise black-and-white) issue. This drawing is from a printer’s proof for one of the images.
