Original poster from 1982 so not a lot of details known. Authentic, right down to the staple holes at the top&bottom since it would have been posted on a Washington DC telephone pole or bulletin board. Scheduled artists at the then-known-for-punk-shows Wilson Center in Washington DC for June 25, 1982: Government Issue, Scream (Dave Grohl's band!), Gang Green, Faith, Artificial Peace, Deadline.
