Estado secreto polaco
Antyk should not be confused with the Social Anti-Communist Committee ("Społeczny Komitet Antykomunistyczny, SKA"), an organization set up by the Home Political Representation on 26 October 1943, headed by Franciszek Białas. Social Anti-Communist Committee coordinated anti-communist propaganda activity among the main political groups and organizations of the Polish Underground State; it also cooperated closely with AK's Operation Antyk.
