SACHEM Advertising Poster, Brooklyn, NY – 1938 A 1938 advertising poster for Captain Jake Martin's "SACHEM" announcing their famous Atlantic City Sea Bass and Porgy trips and daily fishing trips. It is interesting to note that even in 1939, some of the larger boats were expanding their offerings with moonlight sails, Coney Island fireworks trips, a full line of fishing tackle and better food (the ad touts the boat's galley as a modern restaurant.)
