What company makes the trophy for the Super Bowl?

In 1967, Tiffany & Co. former vice president Oscar Riedner made a sketch for the design of the Super Bowl trophy and showed it to Pete Rozelle, who was then the commissioner of the NFL. Since then, the Super Bowl trophy has been handcrafted by Tiffany & Co. in Parsippany, New Jersey. The trophy weighs seven pounds and is 23 inches tall. 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.
