Hi Al

I agree with China, I'd put the picture around 1900 and the landscape format is very unusual, although I do have a couple in my collection...
woman's dress sleeves are not the puffed shoulder that came in during the 1890's.
Hi mrs. tenacious

You are correct that the woman's dress sleeves are not the puffed shoulder that came in during the 1890s...they are a later style, though, not an earlier one

If this photo was 1880s or just into the 90s, you'd expect a very close-fitted sleeve and not one as roomy as this. Also, the photo style is not consistent with this early a date.
I hope you stick around and have a go at some more pictures, we need all the help we can get sometimes!
Cheers
