TITLE: Frank Zappa / Mothers of Invention The Guess Who & Alice Cooper

This psychedelic poster promoted a triple‑bill at the Seattle Center Arena featuring Frank Zappa and the Mothers of Invention, The Guess Who, and Alice Cooper. The event was presented by Boyd Grafmyre with KOL AM and FM.

The artwork was created by John Moehring, known for his Pacific Northwest psychedelic style.

The poster features a central portrait of Zappa surrounded by bright, swirling colors and ornate patterns. Above the portrait sits a winged figure, and below it are clasped hands with Moehring’s signature “#34”.

The lineup is printed vertically along the sides: Left: The Mothers of Invention Right: The Guess Who and Alice Cooper

The bottom text reads: Seattle Center Arena – April 19 – 8 PM Tickets at Bon Marche outlets, Discount Records, Campus Music.

EVENT: Zappa / Mothers concert with Guess Who and Alice Cooper

ERA: 1969 psychedelic rock

TONE: Vivid and avant‑garde AUDIENCE: Seattle rock fans and poster collectors

NOTES: This poster is considered one of Moehring’s finest works, printed on thick textured stock with bright inks that create a near‑3D effect. The lineup reflects the eclectic nature of late‑60s concerts, mixing avant‑garde rock, emerging shock‑rock, and radio‑friendly pop.
