Row of Anchored Sailboats, Lovely Old Oil on Canvas Board Painting, Signed

I just thought--think--this a lovely painting, which my photos do no justice. Oil on canvas board, found in Maine and signed in the bottom left corner, looks like J.G Sandien or similar. With a color punch and impressionistic painterliness to the grasses in the foreground and to the boats and water, too--best understood through details (and hard to capture well in photos white trying to balance with the softer, slightly pinkish sky.) Feels like late day in late summer to me, nicely atmospheric and just a bit melancholic.

14" x 10". Uncleaned as found and clearly previously framed, showing brighter around the far edges where it was covered by the edge of the fame. One small loss to the board at lower left corner.
