Tintype of a young girl and her brother maybe

You have to see this plate to truly appreciate how sharp it is and a really nice pose. And thats one heck of a fringe.
One of my favourites so far.

OldTingirl

Measures 2 1/4 x 3 1/2 inches

And then I saw this one and thought its so similar its got to be the same studio/photographer and that maybe they are brother and sister?

OldTinboy

I bought both tins off the same Ebay seller but at different times.
