The book by Chlebowczyk is focusing on Śliwka's life and handling of his "heritage" by communist authorities after WWII. It is not any controversial, it's a well know story in Zaolzie. As for the details of his biography in Polish see here. As for the street in Karwina, see photo of the street marker on Commons made by me. :) - Darwinek (talk) 22:03, 3 January 2010 (UTC)[reply]
