When the original trailer for Baz Luhrmann's adaptation of F. Scott Fitzgerald's 'The Great Gatsby' came out in May, I respectfully nitpicked its depiction of 1920s Times Square. That same article applies to the new trailer

The Arrow collar sign makes a more prominent appearance here. The original 'Arrow Man' appeared in its most successful advertisements, a dapper model of a gentleman sporting Arrow's signature detachable shirt collar.
The secret behind the ads, created by legendary ad man J.C. Leyendecker, was that the most popular Arrow Collar Man -- model Charles Beach -- was Leyendecker's long-time lover and companion. The pair had lavish parties from their home in New Rochelle during the 1920s, parties which I imagine might have looked a bit like the ones in Luhrmann's film. (Well, I can imagine they looked that way, that is.)
