Handsome Sailor, c. 1920s Real Photo Postcard of Navy Man

I just like the looks of this sailor, standing proud in his uniform as if measuring his girth against the trunk of this large tree. And something about the look on his face makes me think was his sweetheart who took the picture, perhaps just before saying bon voyage!

5 7/16" x 3 1/2 and in very good condition, unused back. C. 1920s I believe.
