MacLean's artwork captures the monikers of the performers: a modern-day Messenger streaks over the Grass Roots growing along the banks of a fast-flowing Mad River.
The three variants of the handbill measure 4 1/2" x 7" and were cut from the pre-concert BG087/088 double-sized mailer.
1st printing A handbill reveals a flying creature with the same color face and body.
1st printing B shows the creature's entire face is lighter than the body.
1st printing C shows the upper portion of the face matches the body and the bottom part of the face is lighter than the body.
During the early days of the Fillmore, MacLean was the most "present" member of the staff. She collected tickets, passed out handbills, blew up balloons and counted money for Fillmore productions. Impressed with her lettering skill on the upcoming attractions chalkboards, Bill Graham surprised her with an easel and art supplies for Christmas, 1967, and MacLean's poster artist career was launched. Untrained in graphic arts, MacLean's early style evolved into ornate, Medieval-Gothic designs. Faces in her posters wore trance-like stares, steady and serene, and evoke the detached spirituality of the sixties.
