"There have been numerous claims regarding the identities of the men in the image. The National Museum of the American Indian claimed to identify three Native Americans in the photo. The movie Men at Lunch traces some of the men to possible Irish origin, and the director reported in 2013 that he planned to follow up other claims from Swedish relatives. The film confirms the identities of two men: Joseph Eckner, third from the left, and Joe Curtis, third from the right, by cross referencing with other pictures taken the same day, on which they were named at the time. The first man from the right has been identified as Slovak worker Gustáv (Gusti) Popovič from the village of Vyšný Slavkov in the Levoča District of Slovakia. Popovič was originally a lumberjack and carpenter. In 1932 he sent his wife Mária (Mariška) a postcard with this photograph on which he wrote, "Don't you worry, my dear Mariška, as you can see I'm still with bottle. Your Gusti." Gustáv and Mária's joint grave in the Vyšný Slavkov cemetery is decorated with the picture. The second worker from the left is Natxo Ibargüen, a native of Balmaseda (Biscay, Basque Country, Spain) and a New York resident since 1924. He is the one with Matty O'Shaughnessy, lighting a cigar."
