On May 21, 1985, in honor of the Owen family's 60 years of promoting in the PNW, a supercard called "60th Anniversary Wrestling Extravaganza" was held at the Portland Memorial Coliseum. The show featured representatives from the NWA, AWA and WWF, including the World Champions of both the NWA and AWA and the World Tag Team Champions of the AWA all defending their titles. The PNW accomplished in this card something the WWF/WWE had yet to achieve, a sold out Coliseum. Barry Owen claimed that this event had the highest attendance ever for a sporting event at the Coliseum. The show saw the final match in the Buddy Rose-Rowdy Roddy Piper angle as its main event, just weeks after both men appeared in the first ever WrestleMania, Rose in the opening match as The Masked Executioner and Piper in the main event against Hulk Hogan. Piper received a hero's welcome from the capacity crowd and pinned Rose to end their long and winding feud.
