This piece of Alaska art is made of all wood. It has strong flowing lines that evoke a running river or a gust of wind. It's a great piece of laser cut wall decor for anyone who loves or lives in the Last Frontier. It is made from three layers of natural white poplar and one layer of natural mahogany, all 1/4 inch thick. There are three sizes to choose from and a variety of color choices. The color will be applied to the middle poplar layer, which makes the layers pop with definition. It has a 1/2 inch backing so it floats slightly off the wall, giving it a nice dimensional look. The backing has a built-in hanger allowing for simple mounting.
