This painting is identified on the back, an oil on canvas adhered to an artist board.  It reads: "Sunset Off Cuba"  August 1861.  Painted by George Teni...? We think it is the work of   the British artist George F Teniswood (1820-1892)    The painting measures 8X11 inches.  Unsigned, in a gold  period frame.  Teniswood was known to sign and title his works on the back and to do small landscape and seascape studies.
