This picture shows a sunset viewed from inside a grotto, with the sun setting over the ocean and casting a golden glow through the opening. Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. The high-resolution artwork behind the hit, coupled with elements of foil, will mesmerize your guests. It is incredibly vibrant and alone will add a dramatic effect to your room. We overbox these large 40x60 pieces of art so they will arrive safely at your home or office. We have also added special hanging hardware, exclusive to Classy Art, to the back to make hanging this piece quick and easy.
