Hi Mirek,
this is B-17G-35-BO, 42-32083 "Flatbush Floozie (or Floogie)" of the 731st BS / 452nd BG. The plane participated in a mission to Berlin on 26 February 1945, was hit and force-landed at Liszki, near Cracow. The area was already back under soviet/polish control and the crew was later returned to England.
Here is another photo of her in flight:
