Fox was one of the first names on the karting and mini-bike scene back around 1959. Many of the early names disappeared following the kart glut of 1962, but Fox survived for quite a while after and, in 1968, was selling an EXCELLENT line of mini-bikes, including the Campus Bike shown on the cover.
This six page catalog featured the "Trail Bike", the "Doodle Bug", the Doodle Bug kit, as well as details on the Campus Bike and a whole back cover dedicated to accessories.
