i'm helping to organize a "bootcamp" with a series of scenarios that EMTs will respond to, and for one of them I am trying to do a mock-MVA. I'd like to have a head injury, with the windshield shattered, so I've been looking for vinyl decals to stick on. I've found lots with fake half sports balls, and a few with flat sports team logos, but I haven't been able to find any without anything in the center. Anyone got any leads?
