Page was from Lynn, Massachusetts & lived from 1850 until 1928. He was a landscape & marine painter & part of a group of artists know as the "Lynn Beach Painters". Experts reckon this was painted in the late 1800's.
In the painting, along with two nice brook trout, you'll see both the fly rod & the fly that was used to maybe catch these trout. Looking at the rod, it's most likely made from Calcutta cane. It's probably a longer rod, of about 10 feet or longer, & it looks to have a leather or celluloid wrap over the grip area. It would have been a cool rod. Also, we can see that some type of bright attractor wet fly was used to fool those beauties.
It's a beautiful painting that I wouldn't mind have hanging on my wall.
