   تخطيط: رأسٌ أبيض بقائمةٍ في الوسط، وواجهةٌ بنفسجيّة فاتحة ببقعٍ زخرفيّة،
   وشريط بحثٍ متقدّم بلون الهويّة يتراكب على حافّتها. عناوين الأقسام في الوسط بخطٍّ تحته،
   وبطاقاتٌ يتبدّل فيها الغلاف بظهره عند الوقوف، وتذييلٌ فيه لوحٌ على هيئة علامة كتاب.
   ألوان الهويّة الخمسة وحدها متغيّرة؛ وما عداها محايد ثابت.
