The IETT company has been running public transportation in Istanbul since 1867. This project I created illustrations and icons for IETT’s strategic planning book. The illustrations are focused on the company's services and Istanbul. The goal is detailed a flexible style to apply in many different places in the report to highlight and enhance different sections. So I’ve chosen simple line illustration style and used two main colors - black and red (which is IETT corporate color). Here are the illustrations, hope you enjoy it.
