This postcard shows a “Cape Ann sloop” sailing through the gap between Straitsmouth Island and Gap Head. The Straitsmouth Island lighthouse is visible in the background.

The postcard was published by Rockport Photo Bureau and printed by The Albertype Co., Brooklyn, N.Y. It has no date or postmark or other markings on the rear. The style of the rear is similar to other postcards I have that are dated between 1920 and 1930, so I’m approximating the date of this as 1925.
