Waterline, Antique Photograph of Five Swimmers

I love an old photo of people in or by the sea, and find this one very beautiful, evoking the sense that these five figures--especially the man at center--were plowing their way through the water, determined to reach the shore. Perfectly punctuating the waterline and framed by the line of the land in the distance.

5 1/2 x 3 3/8 and in good condition, with handwritten names of subjects on reverse.
