My thinking is that Harbour Lights would have to be VERY selective on this type of series. Pharos could be one. The catch is, I imagine the ones that sell best and are dearest to our hearts are those that we may visit or have already seen. The ones that have the most demand (e.g., Portland Head, Hatteras, Southern Belles) are those in prime tourist areas. It's like doing a series of ships that have sunk -- only a few could be successful in the marketplace, such as Edmund or Titanic. The "gone but not forgotten" series would have to choose lighthouses that were either incredibly dramatic (and that could be converted to a great sculpture) or that were world famous (I can't think of too many world famous lighthouses that no longer are standing). So, the bottom line for me is maybe just a few of these.
