Time traveling hipster

Wikipedia:

A photograph from 1941 of the re-opening of the South Forks Bridge in Gold Bridge, Canada, was alleged to show a time traveler. (…) Further research suggests that the modern appearance of the man may not have been so modern. The style of sunglasses first appeared in the 1920s, and in fact Barbara Stanwyck can be seen wearing a similar pair in the film Double Indemnity three years later. On first glance the man is taken by many to be wearing a modern printed T-shirt, but on closer inspection it seems to be a sweater with a sewn-on emblem, the kind of clothing often worn by sports teams of the period. The shirt is very similar to the one that was used by the Montreal Maroons, a hockey team, from that era.
