I have an oil on canvas painting, "Landscape with Cattle", is approximately 39" x 23" . We have been told that it is likely Hudson River School.. It is signed "Stahr" and was sold to my great aunt at least 50 years ago as a Paul C. Stahr, which seems unlikely. I have attached photos of the painting and signature, however, I understand it is difficult to tell much from digital images particularly since I seem to be having trouble with sizing.. If you have any theories as to what this might be I'd be very grateful.. Thank you very much!
