The Beavers played in the short-lived Pacific Coast International League, a Class-B circuit. The Vancouver, BC team relocated on June 25th, moving to Vancouver, WA (guess they wanted to avoid new uniforms). The league itself suspended operations on July 7th. The photo is quite likely from the pre-season.
