The photographer is Nussbaumer at 512 Main Street Buffalo
Notice this photo was called Ivoryette. This is the first time I have seen the very white backgrounds called anything.
This gal is showing lots of neck area for a photo from around 1885-1895.
Mrs. C. H. Avery Buffalo N.Y.Thanks for stopping by.
Update from Iggy:
I think this is Phoebe A Avery (1855 - 1918)
Forest Lawn Cemetery, Buffalo, Erie County, New York
