At the upcoming Fare Thee Well shows, which kick off this weekend in Santa Clara, CA, Participation Row will be distributing a set of limited edition postcards. The postcards were designed by artists Mike DuBois, Jeff Trohldahl and Una Toibin, all of whom have worked with the Grateful Dead in the past. Jessica Muessen also contributed.

To receive a postcard, fans just need to visit one of the 17 non-profit organizations who have info tables on Participation Row and take a designated “action.” Collectively, the actions are dubbed the “17 Ways Deadheads Can Change the World.”

A full list of the 17 actions along with links to each organization can be found here.

“We want to give Deadheads an easy way to be active citizens while at the shows,” said Andy Bernstein, executive director of HeadCount, who organized the giveaway. “Beautiful, collectable art seemed like an appropriate reward for fans who have always had a strong connection to the artwork and causes that sprung up around the band.”
