This photo is of a reference letter, signed by George Scoby Smith, sent to ‘Lyndhurst’ of Roman Road, Linthorpe, dated 23rd October 1917. In this letter, George Scoby Smith describes his driver, George William Porteous, as a careful and competent employee.
George Scoby Smith was the Chairman and Captain of the Cleveland Automobile Club, which had ties to the Royal Automobile Club.
Surely, the way the letter is laid out, it was sent from Lyndhurst, not to that address (which was Smith’s house).
