Super Bowl Trophy
Super Bowl Trophy is made by Tiffany & Co Jewelers since its first inception - 1967. The original design was sketched on a cocktail napkin during a lunch between Tiffany's then vice president Oscar Riedener and the NFL's then commissioner Pete Rozelle in New York City. It takes four months and 72 hours for the trophy to be finished. It is made completely out of sterling silver and the artists that construct the Vince Lombardi Trophy specialize in chasing, polishing, hand engraving, silversmithing, and spinning. The trophy has a stand with three concave sides. On top of the stand is a regulation-sized football that is in kicking position. Engraved on the trophy are the words "Vince Lombardi Trophy," the roman numerals corresponding to that year's Super Bowl, and the logo of the NFL. Details such as the winning team's name and score are engraved after the presentation of the trophy.
