Back then it belonged to Bernard Hailstone- whom the Mail calls a "Royal Artist" on the strength of his having once painted the Queen. I 've come across examples of his work since- and am pleased to report that he was competent and sometimes a little more. All I remember about him is he wore a beard- which was a sure marker of bohemianism in the provinces in the mid-20th century....
I liked his granddaughter but my mate Rupert- who was destined for a career in the Royal Navy- elbowed in between us.
