The movie is set in the 1950s, making this vintage-style Shuron frame a perfect choice for the character. 

The Ronsirs are one of the more significant frame designs of the 20th century. They were the first ever combination frame featuring plastic tops on metal rims with plastic temples and were developed in 1947 by Jack Rohrbach, Shuron's vice president at the time. The frame became a best seller, especially in America, that started a design trend that ultimately affected almost half of all frames sold during the 1950's. Shuron sold more than 17 million of them by 1970. The glasses are also know as "Browline" glasses, which is derived from the fact that the bold upper part of the frames frame the lenses in the same way that eyebrows frame the eyes.

In the film, Robert De Niro plays two characters: Frank Costello and Vito Genovese.
