Robertson, who swapped his first names around to avoid jokes about the Great Western Railway, owned a cottage in the Surrey Hills called Sandhills, in Whitley, near which this pleasant picture was probably set. He was a wealthy man, with many talents; he painted the portraits of fashionable London art world figures, and published an excellent and entertaining autobiography, Time Was, in 1933. He also designed costumes and sets for the London theatre. His watercolours owe much to Burne-Jones, with deliberately chiming colours.
