Armin Hansen's Decoration is the lead lot of an American art auction at Christie's New York.
The painting is expected to make between $250,000 and $350,000 in the September 22 sale.
The auction house explains: "Decoration is a visual celebration of the seafaring life the artist so loved.
"He paints a typical day on the dock as sailors and deck hands chat while, perhaps, repairing and readying rigging and sails for approaching voyages.
"From the piers and docks and wharves, and from the sand beaches and rocky covers Hansen viewed men and their struggle with the sea from countless angles, continuously refining his material over the years, exhibiting up and down the West Coast and occasionally in New York."
The artist's record stands at $390,000, set for a western scene titled First Feel of Leather at Bonhams in 2008.
Grant Wood's study for The American Golfer is another highlight, with a valuation of $150,000-250,000.
Wood was a key regionalist painter whose work is becoming increasingly popular. The final version of the 1940 painting sold for $905,000 at Christie's in 2014.
