Gene Sterling

I have a large framed painting by Gene Sterling titled “Conquistador.” It’s signed and on the back of the frame is a label. I’ve done as much research as I can and I understand the painting is a reproduction of another painting. Evidently Sears Roebuck sold these in the late 1960s.

I frankly don’t care for the painting and am thinking of using the large very attractive frame for a Giclee print.

Would anyone kindly tell me if there’s any value to this painting? If it’s of some use somewhere I’d like to know before removing the painting from the frame. Thank you!
