Craig Ward - Subvisual Subway
The samples were taken using sterilized sponges, from each of New York City’s twenty-two subway lines, that had been pre-cut into the letter or number of the subway line from which the sample was to be taken - A, C, 1, 6 etc etc. The swabs were then pressed into pre-poured agar plates - their circular shape echoing the graphic language of the subway - and incubated for up to a week in his Brooklyn workshop, and photographed at various stages of development before being safely neutralized and disposed of.
