Born three years apart, Helen Frankenthaler (1928–2011) and Jo Sandman (b. 1931) matured absorbing the lessons of Abstract Expressionism. In the early 1960s both artists expanded beyond their painting practices (though never abandoned them) to explore new modes of expression. Frankenthaler began a robust five-decade engagement with printmaking, consistently exploring new media and processes. Jo Sandman moved toward minimalism, simultaneously experimenting with new materials and techniques. Although working independently of one another, the artists, as a pair, point toward new modes of conceptualizing art practice and the important role of printmaking in that revolution.
