Widely regarded as one of the most influential artists of the postwar generation, Polke possessed an irreverent wit that, coupled with his exceptional grasp of the properties of his materials, pushed him to experiment freely with the conventions of art and art history.Constantly searching, Polke studiously avoided any one signature style or medium; his method exemplified the definition of alibi, “in or at another place,” which also suggests a deflection of blame.
