Sorry folks, definitely 1886 & there is no doubt about who they are.
The little guy, my grandfather, was born Jan 1883. Unfortunately I don't have the original. This is a scan of the copy that came to Aus with my grandfather just pre WW1. It was a post card, but a reprint, as were many others he brought with him. There is also a companion pic. of their little sister wearing a similar coat & lace-up shoes & dark socks. I do have an "Original Copy" (Cabinet Card) of the same two boys taken 1883.
I also have in my collection, pics of two of my uncles (unrelated) wearing similar coats, made by their mothers. One taken 1915 with dark socks & laced shoes & the other, 1921, with white socks & open shoes. A fashion revival ??
I'm no expert, but I think Alison's photo is of the same two boys that are in the family group.
