Aramis Antiques has dated this piece to the 1860s.
The watercolour uses body colour throughout, giving the picture a bright and lustrous appearance and this artist was known for this technique. It is signed bottom left. It has a new mount and new glazing within its original frame.

Thomas Charles Leeson Rowbotham was a member of the Royal Institute of Painters in Watercolours and succeeded his father as Professor of Drawing at the Royal Naval School. His work was much admired by Ruskin. He published a number of books of his drawings and sketches and his studio sale was held at Christie’s on 21 April 1876, after his death.
