This picture of Back Beach and its now-gone willow trees appears to have been taken at the same time as another picture I previously posted of the same scene. Not only were both cards published by the Rockport Photo Bureau, but both appear to show the same man sitting on the same bench.
The caption of this one refers to “The Orchard,” which was a tea room and restaurant located across the street from Back Beach, near the present location of the Legion Hall bandstand. There is a small white sign visible just to the left of the car which may be for the Orchard. I do not know what years the Orchard spanned, but I do know it was in business at least during the early to mid-1930s.

Those are locust trees not willows. The locust trees were all along beach street including in front of my parent’s house at 46 Beach Street. We lived there from the early 1930s until the late 1970s. It was a wonderful childhood, with the band concerts on Sunday nights and the fourth of July bonfire, right near our house on the beach! Kay Carter Shumway
