Thank you Irene and Caz
Both very good and much appreciated.
You really had me puzzled Caz about finding another girl's face but after much scrutiny I it does look like someone is sitting some way behind the group in the paddock.
It doesn't look like much of a place to have a picnic or whatever it was they were doing sitting in the dirt. (perhaps food in the suitcase?)
My mother in law said the photo was of her Mother, Father and sister, taken on on the "Queens Domain" (a reserve for the people to use) in Hobart, Tasmania...the photo has 1937 written on the back. Curious.
Thanks again
Jackie
