This is a fan written by Nobusuke Kishi in 1951. It features the Zen phrase "水急不月流" (mizu kyuu ni shite tsuki wo nagasazu), meaning "The water rushes, but the moon does not flow." I found it while sorting through old items. It's mostly unused, but as the photos show, there are some age-related scratches and stains. Please consider this when making your decision.
