Oil Painting of Danish Merchant Marine ship Georg Stage

The painting is held by an intricate wooden frame with beautiful gold paint and black accents.  I don't know the artist or when the piece could have been painted.  Could this be an antique?  Researching what I could gather from the internet, the Georg Stage was built of steel in Fredrikshavn in 1935 to replace the previous Georg Stage as a schoolship for the Danish merchant marine.  She was rigged as a full-rigged ship carrying royals over single topgallant sails and double topsails, and was equipped with an auxiliary engine.  The Georg Stage still serves her original purpose; the trainees stay aboard for five months learning seamanship and related subjects.  She is the smallest sailing full-rigged ship in the world.

If anyone has any other information about this paintings value please feel free to comment.  The painting was a gift from my dad and I am only selling it because my wife isn't fond of maritime art.
