I am familiar with this print, would you like me to value this for you?
Because I am very familiar with what you have. J B Pratt was an engraver that printed many prints by Artist, this is one they did, that was originally ( a painting ) by J H Barnes, he originally painted this in 1881. J B Pratt did many prints from artists.
I can see that the frame is intricate and I can see the print. That is how it can be valued if you like?
