The children’s book titled Optigull and Pesigull: A Good Neighbour Song was published with support from the Bernard Van Leer Foundation as part of the 15th Istanbul Biennial, held between September 16 and November 12, 2017. Burcu Ural Kopan edited the book written by Yekta Kopan and illustrated by Gökçe Akgül. The book tells the story of the enjoyable journey of two seagulls living in Istanbul, Optigull and Pesigull, that takes place at biennial venues. The book was based on a good neighbour, the theme of the 15th Istanbul Biennial. Children reading the book learn new words about the biennial as they come across biennial venues and artworks from exhibitions.

Published in Turkish, English and Arabic, Optigull and Pesigull: A Good Neighbour Song was distributed at exhibition venues for free for the duration of the biennial.
