This is a photo of the complete painting.  Impressionistic, Rhodesian landscape.

The artist was J. Turner.  On the internet, you will find a John Turner 1916 to 2006.  One can not prove at this stage that it is this J. Turner .

It was painted with oil on canvas board. 

A picture paints a 1000 words.  This painting was framed before by ...AAKE (Pvt) Ltd.  Address: 90 Fife Street, Bulawayo. The following information was added by a seller called ""Blisful"" on bidorbuy and had the full name of the picture framer called C. H. Naake (Pvt) Ltd

 A RHODESIAN GLASSED FRAMED PRINT OF A GALLEON, marked to back, " C.H.NAAKE ( Pvt. ) Ltd, PICTURE FRAMES GLASS + PAINT, P.O.BOX 90, FIFE STREET, BULAWAYO, REF. No, 945-56 " width 435mm, height 515mm. The painting was framed in 1956.

The reference number/ job number here was 11076/67.  That tells me it was job 11076 in the year 1967.  It is then possible to say that this painting is close on 50 years old.  It is quite remarkable that this picture framer had a lot of work that went through it's business.  945 orders in 1956 and here already more that 11000 on 1967.

The measurements of the art is 600 x 400 mm.
