I've been collecting antique postcards, especially of lighthouses, for nearly 30 years. Most are from the 1900-1910 period, but some are later. One of my winter projects this year has been to scan more of my collection so I can post them on my site. I now have about 60 postcards in the gallery for the Cape Neddick "Nubble" Light in Maine, and 36 in the gallery for Portland Head Light. If you go through all the lighthouses on my site, you'll see that almost all of them have a postcard gallery.
These cards are often beautiful works of art in
their own right; many are black and white photos that were hand colored by artists. They are also important snapshots of these places at a specific time, thus adding a great deal to the historical records of our light stations.
