Cones N' Cars is a community event hosted by NewTV where attendees bring their classic cars or just come to enjoy the collection on display. The event is sponsored by ice cream vendors that provide the cold treats, and other local businesses to help cover costs.
I pitched an idea to have T-shirts with the backside as sponsorship space. We had seven sponsors on the back of the shirt, we gave them out to attendees for free which led to numerous stories and posts featuring the shirt.
Social and web graphics were also made, as well as sponsorship form flyers and informational flyers for guests.
