The title of Yonca Karaben Sözer’s novel Bir (Doğan Kitap) is Turkish for “one”. Geray Gençer designed a set of four cover variations, with different decorative 1s — customised, based on FF Scala Jewel Diamond, Moku 26 Birch, Bodoni Ornamental, and Ziggurat. Sabre is used for the text and also appears on the back cover.
