A year or so ago I acquired two Harbour Lights post cards. One had the Scituate Lighthouse on it and the other had Thomas Point. These were very nicely done with a color picture of the Harbour Light piece with a famous lighthouse quote on the front and information on the back. A Robert Louis Stevenson quote was on the Thomas Point and a Keats quote was on the Scituate card. Were these part of a series or were they just for put out as a promotion for harbour lights ?
