Swann Auction Galleries said the poster capitalizes on F. Scott Fitzgerald's "The Jazz Age," to depict Carl Fisher's Montauk. The man who had developed Miami Beach focused in on Montauk started, in 1925, to create Miami of the north. His plan included a luxury hotel, The Montauk Manor, which still exists, golf courses and fox hunting.
The poster, which the gallery said dates from between 1929 and 1932, shows all Montauk has to offer, including The Manor. "It is an exceptional representation of the tail end of the Roaring Twenties," the gallery said on its website.
The poster has been restored with some painting and had some tears repaired.
