In 2015 curator Margot Norton selected “Emily Pentacostal” for the biennial, and in 2017 co-curators Beth Rudin DeWoody and Joanna Leonhardt Cassulo chose a portrait of environmentalist Rachel Carson made in a tulip leaf.
Because tulip leaves become semi-translucent in the chlorophyll print process, the Rachel Carson leaf and others have been mounted in float frames.
