I have seen them before. Always wanted to ask about them and have wondered if they were considered lighthouses.
I think that these could be great as accessories like the Bob younger tree or the Boston figurines. Keep it small some where in the $12 to $15 range. Or Produce a batch of 5 or 7 for between $50 to $80 for a particular area. Like the Hudson river, or a inter- coastal water way.
