Jim Mayfield became interested in boomerangs in the mid 1980s. He travelled to boomerang tournaments to compete and collect boomerangs from other top competitors. Jim learned how to make his own rather quickly. He began manufacturing his own boomerangs at his Gunnison Colorado home in the late 1980s. A few years after forming Colorado Boomerangs, Jim sold his company to Richard Pollock-Nelson. Jim worked with Richard after the sale to make sure that the quality of Colorado Boomerang products remained high after his departure. Jim Mayfield was critically injured in a motorcycle accident on 11 October 1999. He died two weeks later at the age of 48, leaving a wife and four young children. Early examples of Jim's products have become very collectable.

This boomerang is the original " Delicate Arch " . It has two small lead weights in each tip and attractive art on the upper surface. Jim Mayfield's signature and the date of manufacture (11 July 1988) was written in ink on the underside. The underside of the lift arm has "Delicate Arch" and "10 ply #1/1" written on it. This one is in mint condition. A wonderful sports boomerang and a terrific collectable.
