Pacific International Livestock Exposition

The Pacific International Livestock Exposition was an annual event that took place in Portland Oregon, beginning around 1910. O. M. Plummer was the exposition's long-time organizer and manager up to 1945. The exposition was housed in a complex of halls in North Portland on the present Marine Drive. During World War II the buildings were used as an assembly center for Japanese Americans being sent to internment camps.
