Jim, while the Niagara connection makes perfect sense,
there are a lot differences between that car (the 1904 Niagara) and the one in our photo.
A lot!
I disagree that that is the car.

And what about the 1897 versus 1904 detail?

Nice photo/painting of two women in front of a waterfall.
With a tree trunk on the right.
Not the same painting.
"conclusively"
lol I'm glad you're not a Lawyer.
now that I look again, maybe not even painted by the same artist (one is very muted, soft and hazy style, the other sharper and more focused)
