By Overnight Post

On 21 June 2013, the night of the Summer Solstice, we observed a stormy sky with a full moon shining through moving clouds. From our apartment balcony, we held our camera and took multiple shots. Later, when we  were reviewing our photographic catalog for potential mail art subjects, the image of the Summer Solstice Moon and brooding clouds seemed perfectly suited for the Cascadia Artpost "By Overnight Post" artistamp.

Unfortunately, due to service reductions by the United States Postal Service, the only overnight mail service available to us here in Olympia, Washington U.S.A. is for mail traveling to the Seattle metropolitan area, 70 miles north, and to correspondents such as Test Tower in Chehalis, about 25 miles to the south.
