Helena Malarewicz Krajewska, born in 1910 in Biecz, worked in easel painting, graphic prints, book illustration, and posters. She graduated from the Academy of the Fine Arts in Warsaw and studied pedagogy. She is also the author of the children's poetry book ‘Paki – Pataki’. She was involved with the left-wing communist-leaning circles. She and her husband, Juliusz Krajewski, were members of the Artists' Club ‘Czapka Frygijska’ (‘Phrygian Cap’) which focused on realist art. She went on many art-inspired trips abroad. During her stay in France, she consulted with Picasso about her work. Kowalska Tower displays works from her Cubist-influenced period, such as ‘Czarna Ala’, ‘Martwa natura kuchenna’, ‘Dziewczynka z fuksją’, and ‘Dziewczynka z płowym kotem’. After the Second World War, after the implementation of the socialist realism doctrine in 1949, she began painting in this style: ‘Tytoniarka’, ‘Przekazywanie Doświadczeń’, ‘Huta Pokój – Stolarnia’, and ‘Budowa Azotów w Puławach’. In 1989, Helena and Juliusz Krajewski donated 200 paintings and several hundred prints – a significant number of their works – to the museum in Biecz.
