Warren Spady, an art student at the University of Oregon in the 1950s, is the creator of the Platypus Trophy. It's the trophy at the center of the Civil War rivalry.
Spady joined me on my radio show on Tuesday to talk about it.
The trophy is two feet wide and 18 inches tall. And it was sculpted from maple in 1959 by Spady, who said, "I never got paid, got no recognition."
It was stolen from the Gill Coliseum trophy case by an OSU fraternity but was recovered. Then, in 1962, someone apparently broke in again and stole it for a second time.
