Here's what I found out from Wikipedia about this cover:

Trybuna Robotnicza (Workers' Tribune) was the old name of Trybuna Śląska – a regional newspaper published in Katowice during the years 1945–2004, one of the largest daily newspaper at that time in Poland, distributed throughout the three provinces: Katowice Voivodeship, Bielsko-Biała Voivodeship and Częstochowa Voivodeship.

The old name was used before 1990, as the regional silesian authority of the ruling communist party (Polish United Workers' Party). After the fall of the communist dictatorship, it was renamed at "Trybuna Śląska" (Silesian Tribune). As a result of selling off the resources of the party publishing house RSW (Workers Cooperative Publishing "Press Book Movement") the newspaper took over the Upper Silesian Press, later bought by the German press concern Verlagsgruppe Passau, publisher of competitive newspaper Dziennik Zachodni (Western Daily). Since 2000, investor gradually limit the scope and number of copies "Trybuna Śląska" and abolished it in 2004.
