Painterly Mid-late 20th Century Watercolor Landscape, Unsigned (With Ink Drawing on Reverse)

I found this and a second larger watercolor landscape listed today at a favorite shop in Vermont--unsigned, but clearly done by an artist who knew what they were doing, mid-later 20th century I believe. (And with an ink drawing on the back of this one that shows they could draw!) Confident, expressive, effortless feeling, fully resolved, to my eye really a lovely thing. 

10 3/4" x 7 1/4", very good condition, with no bleed through from the ink drawing on reverse.
