The listing, Antique POSTCARD Lighthouse / Wharf at FORT WASHINGTON MD Maryland has ended.
Up for bid is a nice antique postcard, copyright 1907, by M.C. Law. View is of the lighthouse and wharf, Fort Washington, MD.
The coloration in the sky part of the card is not surface soiling, but rather how it was printed.
I've been looking around for quite some time, and have not found another one like this, so it may be rare. Card is unused, and in quite nice shape for a 100 year old card!
