This [physics?] text book belonged to Suren Avetissian who was Zara Hakobyan’s great uncle. It was passed to Zara because at aged 18 Suren went to war and during the war died near Rotterdam. Zara still retains other items of Suren’s. The textbook is in Armenian and would have been used by Suren when he was in school in Armenia. Zara choose this from her collection as appropriate to preserve in an archive as it is a book.
