In order for me to properly assess what you have I will need to know the size and see images of the front, back (do not remove from frame) and a clear, in-focus close-up of the signature.
If you had already attached images to your initial posting, they are not showing for me here on my end.
Please send the photos at your convenience. There is not an extra charge to provide more pictures here.
Generally these are commercial decorative wall art paintings and they sell for under $100 on today's market. I can further confirm what you have if you would like to send images.

Just checking in to see if you viewed your answer and if you are seeking further assistance?
Please let me know.
