Vintage Antique Large Oil Painting on Canvas Mediterranean Theam Boats on Ocean

My grandfather purchased this many decades ago, I believe in the 1970's when he retired to live in Arizona. It's unsigned, not sure who that artist is. This piece measures approximately 48" x 24" x 1". It's on canvas and unframed. The colors on this one are very vibrant. Really remines me of a seaside town on the Mediterranean. Overall, it's in nice shape, please see all the pictures, really great classic piece.
