Sunset Beach Wall art. Ready to hang Vibrant artwork for home 20x16, custom

Lovely vibrant sunset scene. The custom artwork of ready to hang. The front is so shiny and vibrant-it was hard to take a good pic without having my reflection in the photo. The backing is about 1 and 3/8 inches so that it is not flat against the wall. I believe it is a “box mount” on aluminum. with a shellac-type finish. The piece has never been used and is in excellent condition. My brother took the photo at Pensacola beach but has decided to to hang it after all. Please see images for measurements.
