Nasza Księgarnia (Our Bookstore) is the oldest publisher of children's books in Poland.
[5] It was founded by Związek Nauczycielstwa Polskiego (English, "Polish Teachers' Union") in 1921 as a joint stock company.
[6] Among the company's other Polish language editions of children's books over the years have been Astrid Lindgren's Pippi Longstocking and Tove Jansson's Moomins.
[5] During World War II, Nasza Księgarnia continued to release new books, only changing its forms, adapting them to the conditions of underground work.
During the political and economic changes in Poland during the early 1990s the state-owned enterprise was transformed into a limited liability company.
