The photographic series entitled "Minus One" was created by Hanna Anderman (alias Anna Musiałówna) in 1970s. It was not published in the official press as it broke taboo about abortion in Poland. It might be considered as a symbol of a part of everyday life in socialist Poland that the authorities did not want to show to wider audience.
State politics towards women's reproductive rights varied in the socialist times. After the "Khrushchev Thaw", from 1956, the termination of pregnancy was possible in the situations of not only medical conditions of woman or fetus, but also hard living conditions of pregnant women. However, the abortion was not discussed publicly until the 70s when Polish sexologists started to publish their books on sexuality, procreation, and contraception. The debate about termination of pregnancy concentrated on the fact that due to low social awareness and accessibility of contraception the number of abortions, especially those performed in the unsterile and unofficial conditions, was too high. At the same time, the wider public was not exposed to bare documentation of the act of termination of pregnancy itself, which is the case in Musiałówna's photographic cycle. 
In order to gain access to the hospital performing the termination of pregnancies Musiałówna had to use her best capacities as researcher and reporter and it cost her months of preparations. She photographed the procedure in a hospital and showed the medical utensils, figure of white-clad doctor, drops of blood and silhouette of a fetus. The photographs were bluntly showing the very core of the preparations for procedure, yet at the same time, as they were black and white, they did not shock with drastic images of blood. It is a very interesting cycle, combining together the sensitivity and craftsmanship of a photographer with a very important social issue.
