Sailboats on Water, Antique British Monochromatic Ink Wash Postcard

This ink wash seascape is pretty understated, but I think makes for quite an elegant, and also a bit melancholic, old postcard, c. 1910s British, I believe. The monochrome palette also makes it feel sort of mid-way between watercolor painting and black and white photograph, at a time when one was giving way to the other, which for me rather enhances its end-of-the-day feeling.  

3 1/2" x 5 1/2" and in excellent condition, with unused back.
