Folding card with a photo of Marcia on the front and text inside (in part): "One evening of ten years 'Art by Marcia Clay' at the home of Richard Brautigan who will read (don't worry, briefly) six or seven poems of his last ten years." Enclosed in the original mailing envelope (roughly opened) partially addressed by Brautigan who has written his name in the return address portion and the words "Mr. and Mrs." on the front. Fine. Impossibly rare ephemera, we've never seen or heard of this.
