Mural Arts Philadelphia has always focused on the big themes: art, community, social change. For their 2013 Wall Ball invitation, we wanted to bring these big picture ideas to life in a way that was interactive and lasting. The result was an invitation designed around the theme of photography: the envelope looked like a camera, and the invitation inside turned into a usable picture frame. We engaged invitees by asking them to go out into their community and take pictures of the murals they found, sharing them with the social media community with a hashtag. Contributing their own photos to Wall Ball made invitees feel part of something bigger, and the frame keepsake let them display their own art and memories at home.
