74 1966.0068.001 Cap hub Brass COMET   Unknown Unknown             1   Hub caps are collector's items. Cover put on automobile wheels to enhance its aesthetic appearance or aerodynamism and to protect the wheel bolts from mud and dust. Originally hub caps date back to the horse-drawn era and afterwards to the first automobiles when wheels were made of wooden spokes connected to the center hub. The hub contained the wheel bearing which was packed with grease. The hub cap was a small device used to cover the center hub to keep the dust out and the grease in. Eventually car manufacturers replaced the wooden spokes with steel wire spokes in the 1920¬ís and 1930¬ís. As a result the hub cap evolved into a wheel cover which is a large disc that covers most of the wheel. Wheel covers continue to serve a functional purpose but they have also become a decorative design feature of the wheel .
