This image shows a rock formation along the coastline of Bailey Island, Maine, which is given the colorful name of Pirate’s Cave.
H.J. Burrowes Company, Portland, Maine
The description states:
PIRATE’S CAVE
Bailey Island, Maine
–The cave is difficult to make out in this image, but is presumably the darkened area in the center. The rocky foreshore seems an unlikely place for a landing, and the label may be just a promotional effort by the makers of the postcard.
This image likely dates from the 1940s.
