I’m also selling t-shirts and apparel based on MUNI, the San Francisco public transit system. I sell them through four brick and mortar stores in San Francisco
Brand Fury – 780 Sutter Street
The Artist Exchange – 16th and Guererro
MotoJava Cafe – 9th and Bryant
Mission Cliffs – 19th and Harrison (coming soon if there’s enough demand)
SoMe – Haight and Masonic
I also sell them through CafePress. They are a print-on-demand website so I can offer all of the bus and train lines. Go to the website to see them.
