Halftime stunt during 1939 Homecoming football game against California. Doug Chambers is in the beaver suit, commissioned by the Rally Squad for $10. The suit was used for at least three games in 1939 and 1940 and had a four-foot tail that was "stiff as a board." The costume is the earliest known beaver costumed used at Oregon State, though it is not considered part of Benny Beaver's lineage.
