Yes, that is an excellent find. One of my hobbies is collecting original examples. I recently acquired a J. E. Purdy (Boston) portrait of Dorothy Stanley Emmons. She was daughter of Chansonetta Stanley Emmons, who herself was an accomplished photographer. They were from the Stanley dry plate / Stanley Steamer family.

I believe Purdy's was a studio with multiple locations throughout the Boston area. There is an early article on Purdy @ goole books (starting pg. 128). Hopefully you can access it . . .

As far as displaying . . . some photographs adorn the walls, while others are kept safe.
