Chatham Marconi Wireless Station Postmark

A postmark to commemorate the 100th anniversary of the Marconi Wireless Receiving Station in Chatham Massachusetts. It was built to replace the Cape Cod station that was slowly being destroyed by natural forces, having been built too close to the ocean. The receiving station at Chatham was used in conjunction with the transmitting station in nearby Marion for ship to shore wireless communication. The site is now home to the Chatham Marconi Maritime Center museum.
