  We examine the shadow cast by a Kerr black hole pierced by a cosmic string.
The observable images depend not only on the black hole spin parameter and the
angle of inclination, but also on the deficit angle yielded by the cosmic
string. The dependence of the observable characteristics of the shadow on the
deficit angle is explored. The imprints in the black hole shadow left by the
presence of a cosmic string can serve as a method for observational detection
of such strings.
