The goal of this article is analysis of epistolary signatures (autographonyms) of selected writers of the 20-year interwar period (M. Choromanski, M. Dabrowska, W. Gombrowicz, J. Iwaszkiewicz, Jan Lechon, B. Lesmian, M. Samozwaniec, B. Schulz, J. Tuwim, and S. I. Witkiewicz) and their appearance as pseudonyms. Described are the sociological, psychological, and pragmatic conditions of their selection and the means of creating the autographonyms assembled as well as formal classification of them. The specificity of the epistolary signature is emphasized, as it was often a fulfillment of the expression of partners in correspondence dialog as well as a determinant of the emotion and expression of the letter’s author.
