The photographs were reproduced on photographic paper at the printing house of the Lviv-based publisher Książnica Atlas. Its photomechanical department was directed at the time by Witold Romer, who conceived a special method of replicating photographs by using secondary negatives, first applied in the production of the Książnica Atlas' famous series of tourist postcards (which, by the way, also included Mierzecka's photographs). The same method was used to reproduce Mierzecka's photos from the cycle Ręka pracująca, where the artist prepared her own secondary negatives.
The book was first released as a manuscript in the summer of 1939 in two hundred and fifty copies. In 1947, another seventy-five copies of the book were produced out of the preserved and printed but not bound sets. This specific 'reprint' includes the information that the first edition was lost during the war and only the review copies were saved. Meanwhile, Mierzecka writes in her memoir (Całe życie z fotografią/Whole Life with Photography, 1981): 'Two hundred and fifty copies sold out in no time and I don't know how it was possible that about seventy unbound sets 'survived' the war.' In the same text, Mierzecka quite rightly refers to the book published together with her husband as 'one of a kind.'
