Earlier this year we introduced The Brief, an ongoing feature that asks the advertising and creative community to come up with ideas on how to tackle gun violence in the U.S. For the student-inspired March for Our Lives on March 24, we partnered with the Gun Safety Alliance on a more specific brief, one calling for work that supports those who will be marching in Washington, D.C., and across the country. The assignment: Create posters and social media imagery that can magnify the students' messages.

The community responded in spades, with more than 100 pieces of art, some of which traveled all the way into the hands of the marchers and onto billboards in Times Square (see above). Check out (and download) the full collection here.
