There’s a terrific article by Benjamin H. Trask on Postcard History titled Coastal Sentinels: United States Lighthouses. I’ve always been captivated by the solitude of a lighthouse keeper’s life. I’m actually somewhere between fascinated and disturbed by what that life must have been like. And that interest continues with lighthouse postcards. I buy them whenever I see them. But what I have pales in comparison in what exists. Trask writes in the intro:

A thread of shoreline with a lighthouse has long been a focal point for artists and photographers as well as a destination for tourists and lovers. At the close of the postcard’s golden era, around the outbreak of World War I, America boasted more than 1,400 lighthouses tended by resident keepers.
