In conjunction with the June 2007 USPS release of their Pacific Lighthouses stamps, Harbour Lights created 1,500 of these sets to capitalize on the popularity of the stamps. The lighthouses depicted in the stamps are St George Reef, CA, Diamond Head, HI, Five Finger, AK, Grays Harbor, WA. and Umpqua River, OR. ?Each individually numbered set includes the five lighthouses as LLOM’s. The lighthouses are packed into a five compartment wooden box with a sliding top. Also included with the lighthouses are an actual set of the five USPS stamps.
