Obviously, personal seals printed on manuscripts provide information about their owners. Most of these seals consist of beautiful calligraphic samples and patterns. There are different seals among the memorial things, personal belongings of the prominent poets and writers of Azerbaijani people demonstrated in the exhibition of the National Museum of Azerbaijani literature named after Nizami Ganjavi. The article is about the seals belonging to M.F.Akhundov and his family, Ali Nazmi, N.Narimanov, Jalil Mammadguluzadeh, E.Aghaev, Javad Heyat. These seals cause great interest in each visitor to the museum.
