Illinois 15 (Illinois) (Road Sign) T-Shirt: Design Description
This t-shirt features the iconic road sign for Illinois Route 15 (IL 15), a major east-west highway traversing the southern portion of the state. The design is a faithful representation of the modern Illinois state route marker.
Visual Elements
The artwork centers around a crisp, white square, bordered by a clean, black line. Centered within this square is the highway designation. Above the numeral “15” in bold, sans-serif font, the word "ILLINOIS" is printed in the same black color. The arrangement is simple and highly legible.
Representation and Symbolism

The black-on-white color scheme, a design standard since the 1950s, signifies a streamlined, standardized approach to wayfinding, offering clear and concise information. The bold, simple lettering ensures easy recognition and readability at a glance, allowing for quick and efficient identification for drivers.
