The artwork on the back is a technical illustration from Garrett A. Morgan’s groundbreaking 1914 patent for the Safety Hood and Smoke Protector — an early breathing device that later influenced the modern gas mask and revolutionized firefighter safety.

The diagram on the shirt displays:

• Morgan’s original mechanical sketches

• Labeled components of the breathing hood

• The airflow and filter system he engineered

• Authentic patent-style linework and annotations

This invention saved countless lives and stands as one of the most important early innovations in public safety.
