I recently came across Harbour Lights at a shop while on vacation. I love lighthouses and have thought about collecting them for a while (I have many prints around the house). After checking the HL website I realized how many there are in the collection. I am from Melbourne, FL and was curious as to how hard it would be to try and collect just lighthouses of Florida. I have a print signed by a local artist of all of the FL lighthouses.

How difficult is it to get retired pieces?
Is it possible to get past special editions?
How can I find out about future releases of other FL lighthouses? (I saw only 13 released so far out of over 25+ lighthouses in Florida that I know of)

Thanks in advance for any asistance - KR
