The paper discusses the history of Clara Bernthal, a postcard publishing house from Gdańsk founded in 1898. The author provided information about the founder of the publishing house and the postcards on the basis on the archival materials. The text has been supplemented by a catalogue of Clara Bernthal postcards from Biblioteka Gdańska’s holdings. Collectors, museum registrars and librarians will find this information helpful in identifying publication dates of the postcards.

This article aims to analyze the subject matter of Polish informative and reporting utterances (IRUs) extracted from messages sent by postcard. In addition to analyzing the subject matter of IRUs, the article aims to formulate hypotheses about the reasons for discussing specific topics. In addition, the characteristic linguistic devices used in IRUs are described. The considerations show that the subject matter of IRUs is primarily shaped by the text patterns of postcard letters, the relationship of the interaction partners, and their gender.
