Unsure about this painting. Oil on canvas. "Faure" is on bottom right. I found a similar painting but much smaller online with the artist Eugene Faure. inside frame measurement 23 1/2 x 35 1/2
Painting has been in the family for over 40 years. Unsure where it was bought
Your painting is quite intriguing and looks much more recent than the smaller work by Eugene Faure sold a few years ago by DejaVu Estate Sales & Auctions, Florida:
This is probably a copy, but my immediate advice is that speak directly with this auction house for a second opinion. Their details can be found here:
For your information, works by Eugene Faure (1822 -1878) are around $2000 and $3000.
I hope this helps.
