Long Beach Island, NEW JERSEY - "Six Miles at Sea" - Artist:  Bill Kane:  Long Beach Island (colloquially known as LBI or simply The Island) is a barrier island and summer colony along the Atlantic Ocean coast of Ocean County, New Jersey in the United States. Aligned north to south, the northern portion has generally more expensive low-density housing, whereas the southern portion possesses higher-density housing and considerable commercial development. The primary industries include tourism, fishing, and real estate. The only access point to the island by land is a single causeway.  The island is home to about 20,000 people on a year-round basis. The population is distributed among six separate municipalities, the largest of which is Long Beach Township.  This Linen Era (1930-45) postcard is in good condition.  Beacon Times Print.
