very dodgy...... you should get enamels 1000 to ask his local neighbour as mr hockney lives a stones throw away from him on the east coast , judging by the price of repros eg the the small pratts sign or actual paintings people are still geting caught and always ask or find more info after the deal is done ,,,,my best advice is , ask first then purchase ,,, these scammers dont have a concience,,,,,
