As part of her ongoing series titled Traveling Landscapes, New York-based artist Kathleen Vance constructs entire landscapes inside of old steamer trunks and repurposed luggage. Many of the pieces incorporate real running water, soil, and living plant life to form encapsulated environments, though others are constructed from common model making materials and resin.
