Windsor Castle

The price label of 15/6 for this 350 piece P.6 Popular Series plywood puzzle indicates a production date of post 1959.
The painting is by the British artist Max Hofler (1892-1963), whose works features elsewhere in this Chad Valley puzzle, another of his river scene studies. See also the closely-matched Popular Series puzzle Houses of Parliament, which also features his work and was probably produced at around the same time.
