Thank you, amazing people. Following all your inspection of the details I had another look too, and am sure that the 'gipsy' on the left of the 'Scot' is my grandmother, and the man behind the sailor boy is my mother's uncle dressed as 'John Bull'. He had lived in America before the war, hence my confusion. Around this time they lived in Clinton St. My own guess is that it was an end of WW1 celebration. My mother would have been about eight. I think the sign definitely says 'Khaki' but don't know what it means. If anyone knows anything about such a carnival I'd be delighted to know. And is there anywhere I should send this photo for preservation as I doubt my children will be interested.
