This mosaic is a relic from socialist propaganda days.
Made in 1964 by W. Zych, it commemorates the attacks on the Café Club on the corner of Jerusalem Avenue and Nowy Swiat.
During the occupation, the "Café Club" was only available for Germans (Nur für Deutsche).
People's Guard made a double attack on the Café Club (October 24, 1942 and July 11, 1943).
