Specially designed for the Estonian Maritime Museum black notebook a  with a picture of the Cog. The notebook comes with a blue ballpoint pen.

The Cog is a sailing ship widespread in medieval Northern Europe, used as both a merchant and a warship. Such sailing ships were distinguished from others by their belly, large cargo spaces and one large mast and scraper. The Cog was mainly used in the 13th-17th centuries, when the Hanseatic League was active, whose members were connected to the waterway.
