Fighting Poland symbol instances

"In the first months of 1942, the Polish underground Information and Propaganda Bureau announced a competition for the design of symbol for the Home Army. Out of twenty-seven projects, Smoleńska’s Kotwica was selected as the most legible symbol. The sign combined the letter P for Polska and W for Walcząca [fighting]. One of the reasons for its selection was that it was relatively easy to draw or paint in clandestine settings."
