This is a a vintage postcard view of Dunmere at Narragansett Pier, Rhode Island. There is no date on the card, but it is a tinted photo of the landmark and looks very much like other cards I've seen dated around 1900-1910.

This card was never used.

There is a Dunmere Bed & Breakfast today! Click here to visit their web page and see a photograph of the same scene as in the postcard.
