Ericka Walker (born June 16, 1981 in Hartford, Wisconsin) is an American artist and printmaker. She lives and works in Halifax, Nova Scotia, Canada. Walker is noted for using traditional and digital printmaking tools and techniques to design and print large-scale contemporary lithographs that emulate turn of the century propaganda posters. Her work reflects contentious U.S. foreign policy issues and the implications of endless occupation through the use of nostalgia as a means of questioning persistent domestic relationships between industry, agriculture, and mechanized warfare.
